Design System Inspiration of Toss Securities (토스증권)

1. Visual Theme & Atmosphere

Toss Securities positions itself as an investment platform for both beginners and experienced investors: the company says its mission is to empower everyone with investing, combining access to global markets, investment information, social participation, and expanding channels such as WTS. Its public web language turns that broad promise into a familiar Toss hierarchy—white canvas, dense dark-neutral reading text, a precise blue action color, and a single Korean-first product face—rather than turning the marketing site into a simulation of a trading terminal. The result is an inviting, information-led public entry point for a regulated investment product.

The supplied 2026-07-13 capture establishes three separate public domains. www.tossinvest.com is a public WTS surface with controls, tabs, a menu, and a dialog; home.tossinvest.com/en/corporate-info is corporate context; and home.tossinvest.com/en/investment-products is a marketing explanation of stocks, ETFs, options, and bonds. They share #3182f6, #ffffff, #1a1f29, #4e5968, and Toss Product Sans, but their component geometry is not automatically interchangeable. The compact 32px WTS action and the 40px marketing pill are recorded separately.

No authenticated account, native app, order-entry flow, or documentation UI was captured in this packet. The former dark-canvas, red/blue market-semantic, token-tree, and two-radius claims are therefore removed rather than carried forward from a legacy snapshot.

Key Characteristics:

• Light public-web canvas: #ffffff, #1a1f29, and #4e5968
• Shared Toss blue #3182f6 for observed primary actions and links
• Loaded Toss Product Sans on the public WTS and investment-marketing surfaces
• Compact WTS controls at 7–8px corners; expanded menu and dialog containers at 12px and 16px
• A 100px-radius marketing pill is a marketing-specific component, not a universal product radius
• Public WTS menu and dialog were interaction-expanded; focus, hover, and pressed states are preserved only where observed
• Measured pointer states are quiet: WTS tabs deepen their text alpha on hover, segmented radios and content cards take a 2% then 4% navy wash, and the investment-products header links turn Toss blue #3182f6

Primary tasks

• Choose among domestic and overseas stocks, ETFs, options, and bonds
• Trade through the public web trading surface in a browser
• Read investment information and take part in the community

2. Color Palette & Roles

• Primary action (#3182f6): observed on the public WTS compact primary action and the investment-products marketing CTA.
• Canvas (#ffffff): observed public WTS and marketing page canvas.
• Foreground (#1a1f29): observed compact WTS foreground.
• Supporting text (#4e5968): observed WTS menu, dialog, and cross-surface supporting text.
• On primary (#ffffff): observed text on #3182f6 actions.
• Dialog canvas (#fbfcfd): observed public WTS dialog container.

The packet does not establish a public positive/negative market-color system, dark trading canvas, error color, or success color. Those values are intentionally absent rather than inferred from the Toss parent brand or a previous snapshot. Hover and pressed treatments were measured as translucent navy washes and text-alpha steps (§4, §14), not as new opaque palette colors; the one opaque state color is #3182f6 on the investment-products header links.

4. Components

Public WTS compact primary entry

Default / focus / pressed

• Background: #3182f6
• Text: #ffffff
• Radius: 8px
• Padding: 6px 12px
• Height: 32px
• Font: 14px / 600 / 16px Toss Product Sans
• Focus: observed; retained color and geometry remained unchanged. The frame followed a mouse press, so it is not a keyboard :focus-visible measurement.
• Pressed: observed; retained color and geometry remained unchanged (only an alpha-0 inset-shadow width moved, 1px to 0.98px; the style dump records no opacity, outline, or transform)
• Use: public WTS compact link-action at home::[data-omd-capture="6"]

Investment-products marketing primary

Default

• Background: #3182f6
• Text: #ffffff
• Radius: 100px
• Padding: 11px 14px
• Height: 40px
• Font: 15px / 600 / 18px Toss Product Sans
• States: default only. The capture holds no hover, pressed, or focus sample for surface-3::[data-omd-capture="11"]; the state samples on this page belong to the same-class (css-f411df) secondary pill described below. Corrected 2026-09-29; the July text had attributed them to this action.
• Use: investment-products marketing action at surface-3::[data-omd-capture="11"]

• Use: public WTS tabs (role=tab) at home::[data-omd-capture="13"] and home::[data-omd-capture="14"]; selected sample home::[data-omd-capture="12"]

Public WTS segmented radio

Unchecked / checked / hover / pressed

• Background: transparent
• Text: rgba(18, 31, 51, 0.47) unchecked; rgba(26, 31, 41, 0.89) checked
• Radius: 5px
• Padding: 0px
• Height: 24px
• Font: 16px / 400 / 18.4px Toss Product Sans
• Hover: fill rgba(13, 25, 74, 0.02)
• Pressed: fill rgba(7, 25, 76, 0.04)
• Use: role=radio options at home::[data-omd-capture="18"], "19", "22", and "23", which all record the same values; checked sample home::[data-omd-capture="17"]

Public WTS content card link

Rest / hover / pressed

• Background: transparent
• Text: #4e5968
• Radius: 12px
• Padding: 4px
• Size: 248px x 176px
• Font: 16px / 400 / 23.2px Toss Product Sans

• Pressed: fill rgba(7, 25, 76, 0.04), the same wash the compact menu trigger carries at rest
• Use: content card link at home::[data-omd-capture="11"]

Public WTS top navigation link

Rest

• Background: transparent
• Text: rgba(22, 31, 46, 0.61)
• Radius: 9px
• Padding: 8px 12px
• Height: 36px
• Font: 14px / 600 / 20px Toss Product Sans
• States: hover, pressed, and focus frames were sampled but caught the colour transition in progress (text alpha between 0.627 and 0.667, different per link), so no state value is declared
• Use: top navigation links at home::[data-omd-capture="2"], "3", and "4"

Public WTS compact menu trigger

Rest / expanded

• Background: rgba(7, 25, 76, 0.04)
• Text: rgba(26, 31, 41, 0.89)
• Radius: 7px
• Padding: 4px 8px
• Height: 28px
• Font: 13px / 600 / 20px Toss Product Sans
• Shadow: rgba(0, 23, 51, 0.02) 0px 0px 0px 0.5px inset
• States: the captured menu interaction expanded it (expanded, menu-open); no pointer-state frame was sampled for it
• Use: menu trigger at home::[data-omd-capture="27"], which opened the expanded menu above

Public WTS dialog text field

Dialog-open

• Background: transparent
• Text: rgba(0, 12, 30, 0.8)
• Radius: 0px
• Padding: 0px
• Height: 17px
• Font: 15px / 600 / 17.25px Toss Product Sans
• States: observed only inside the opened selection dialog; no pointer-state frame
• Use: text field at home::[data-omd-interaction-capture="dialog-1-2"]. The input element itself is borderless; its visible frame belongs to a wrapper the capture did not sample, so no field border or fill is claimed.

Investment-products header navigation link

Rest / hover / pressed

• Background: transparent
• Text: rgba(253, 253, 255, 0.75)
• Radius: 0px
• Padding: 0px 8px
• Height: 14px
• Font: 14px / 600 / 14px Toss Product Sans
• Hover: text #3182f6
• Pressed: text #3182f6
• Use: eight header links, surface-3::[data-omd-capture="1"] through "8", and the header button "9" record the same rest and state values. The light text implies a dark backdrop, but the backdrop's own fill was not part of the sampled elements and is not claimed.

Investment-products secondary pill

Rest

• Background: rgba(2, 32, 71, 0.05)
• Text: rgba(3, 18, 40, 0.7)
• Radius: 100px
• Padding: 11px 14px
• Height: 40px
• Font: 15px / 600 / 18px Toss Product Sans
• States: hover, pressed, and focus frames were sampled but differ only by transition-frame deltas (fill alpha 0.05 to 0.055, inset-shadow width 1px to 0.90–0.98px), so no state value is declared
• Use: secondary pill at surface-3::[data-omd-capture="13"], sharing the css-f411df class and 40px geometry with the blue primary

Only selectors, surfaces, and states present in the supplied raw collector evidence are described here. The capture did not establish native-order, toast, error, disabled, or checkout variants; the content card link is the only card-like control sampled. Focus frames exist for some controls, but the collector pressed the mouse before calling .focus(), so no focus value in this reference is a keyboard :focus-visible measurement.

5. Layout & Spacing

The observed public WTS uses compact 4px, 8px, 12px, and 16px spacing clusters; the investment-marketing CTA contributes a 14px horizontal inset. Treat this as a small observed set, not as a complete spacing scale. WTS has square-edged tabs, 7–8px compact controls, a 12px menu, and a 16px dialog; the marketing pill’s 100px radius belongs only to that action.

6. Iconography & Imagery

The public WTS capture shows compact control and text-led UI; the expanded menu and dialog establish interaction containers but not a reusable icon family. The investment-products page uses product imagery and explanatory marketing content. No proprietary chart, illustration, or native-app icon system is promoted from this evidence.

7. Usage Guidelines

Do

• Keep public WTS compact actions distinct from the 40px marketing pill.
• Use #3182f6 with #ffffff for the observed primary action pairing.
• Preserve the recorded WTS container progression: 12px menu, 16px dialog.
• Use Toss Product Sans where the verified public web family is available; label unavailable specimens rather than substituting a system face as if it were Toss Product Sans.
• Limit interaction claims to the sampled states: WTS tab and segmented-radio hover and pressed, content-card hover and pressed, investment header-link hover and pressed, the compact primary's pressed frame, expanded/menu-open, and dialog-open. Focus frames were not keyboard-measured.

Don't

• Reintroduce an unverified dark trading canvas or red/blue market semantics from the legacy snapshot.
• Treat the corporate or investment-marketing page as proof of authenticated or native trading UI.
• Generalize the 100px marketing pill to WTS controls.
• Promote Tossface to the UI family merely because it is declared in the stack.
• Invent disabled, error, loading, toast, or checkout variants, or card treatments beyond the sampled content card link.

8. Accessibility & Density

The public WTS samples use #1a1f29 and #4e5968 on light surfaces, while primary actions use #ffffff on #3182f6. The packet establishes visible selected and unselected tab/radio controls plus menu and dialog expansion, but it does not provide a full keyboard, screen-reader, contrast, disabled, error, or responsive audit. Retain the observed state distinction and perform a product-specific accessibility audit before extending it to account or order entry.

9. Voice

The official corporate language is direct, inclusive, and opportunity-oriented: it frames the service around better investment experiences, access to global markets, and technology that makes investing easier. The samples below are original tone guidance, not verbatim Toss Securities copy.

• “See the choice clearly, then decide.”
• “투자를 더 쉽게, 다음 기회를 더 가깝게.”
• “One account, more ways to invest.”

10. Voice & Tone

The examples in §9 are illustrative paraphrases only; no tagline or customer promise is reproduced as official copy.

11. Brand Narrative

Toss Securities is a Korean securities company building an investment platform around the mission “To Empower Everyone with Investing.” Its official company page describes an aim to offer better investing experiences and access to opportunities in global capital markets.

The current public company narrative expands that scope from stock trading toward an inclusive platform for beginners and experts, with investment content, a social community, broader investment products, and WTS access. Its investment-products page makes the portfolio breadth concrete through domestic and overseas stocks, ETFs, U.S. stock options, and overseas bonds.

The company page also records current international expansion milestones, including a U.S. broker-dealer license in 2025. This is company context, not a claim about any uninspected product interface.

12. Principles

1. Opportunity should be broadly reachable. The stated mission is to empower everyone with investing. UI implication: explain product choices and next actions without presuming expert knowledge.
2. Global-market access should feel connected. The company describes global products and WTS as access channels. UI implication: make market, product, and account context explicit rather than relying on implicit navigation.
3. Technology should make investing easier. The official narrative connects technology and AI with better decisions. UI implication: present information as decision support, not as a promise of outcomes.

13. Personas

These are official audience-scope archetypes, not user-research findings or synthetic satisfaction scores.

• Beginning investor: the company explicitly names beginners among the people its inclusive platform should serve. Use plain explanations and visible product context.
• Experienced investor: the same platform is intended to include experts. Keep high-information paths available without representing unobserved native or authenticated UI as canonical.
• Cross-market investor: the official product range includes domestic and overseas investments. Make product and market boundaries explicit.

14. States

15. Motion & Easing

No duration, easing, or transition token was measured in the supplied evidence. The captured hover, focus, pressed, menu, and dialog snapshots establish state presence only; they do not authorize a motion scale. Several state frames were caught mid-transition (fractional inset-shadow widths, text alpha that differs link to link), which shows that transitions exist but not their duration or easing. Keep any future motion specification separate until first-party computed transition evidence is available.
