Robinhood UI Skills
Opinionated constraints for building Robinhood-style interfaces with AI agents.
When to Apply
Reference these guidelines when:
- •Building dark-mode interfaces
- •Creating Robinhood-inspired design systems
- •Implementing UIs with Inter font and 4px grid
Colors
- •MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 0
- •MUST use
#000000as page background (surface-base) - •MUST use
#B7DF2Ffor primary actions and focus states (accent) - •SHOULD limit color palette to 10 distinct colors
- •MUST maintain text contrast ratio of at least 4.5:1 for accessibility
Semantic Tokens
| Token | HEX | RGB | Usage |
|---|---|---|---|
surface-base | #000000 | rgb(0,0,0) | Page background |
surface-raised | #C3FE09 | rgb(195,254,9) | Cards, modals, raised surfaces |
text-primary | #A0A0A0 | rgb(160,160,160) | Headings, body text |
text-2 | #ECECEC | rgb(236,236,236) | Additional text |
text-secondary | #497009 | rgb(73,112,9) | Secondary, muted text |
border-default | #B7DF2F | rgb(183,223,47) | Subtle borders, dividers |
accent | #B7DF2F | rgb(183,223,47) | Primary actions, links, focus |
Typography
- •MUST use
Interas primary font family - •SHOULD use single font family for consistency
- •MUST use
85px/700for primary headings - •MUST use
14px/400for body text - •SHOULD reduce font weights (currently 4 detected)
- •MUST use
text-balancefor headings andtext-prettyfor body text - •SHOULD use
tabular-numsfor numeric data - •NEVER modify letter-spacing unless explicitly requested
Text Styles

text-17px | Inter | 17px | 400 | #A0A0A0 | 1 |
body | Inter | 14px | 400 | #A1A1A1 | 2 |

Typography Reference
Font Families:
- •
Inter(used 13x)
Font Sizes: 11px, 14px, 17px, 18px, 85px
Spacing
- •MUST use 4px grid for spacing
- •SHOULD use spacing from scale: 4px, 5px, 6px, 12px, 13px, 14px, 17px, 19px
- •SHOULD use 4px as default gap between elements
- •NEVER use arbitrary spacing values (use design scale)
- •SHOULD maintain consistent padding within containers
Borders
- •MUST use border-radius from scale: 19px, 21px
- •SHOULD use 21px+ radius for pill-shaped elements
- •SHOULD limit border widths to: 1px, 2px
- •SHOULD use 21px as default border-radius
- •NEVER use arbitrary border-radius values (use design scale)
- •SHOULD use subtle borders (1px) for element separation
Border Radius Reference
Scale: 19px, 21px
Layout
- •MUST design for 1920px base viewport width
- •SHOULD use consistent element widths: 12px, 74px
- •SHOULD maintain text-heavy layout with clear hierarchy
- •NEVER use
h-screen, useh-dvhfor full viewport height - •MUST respect
safe-area-insetfor fixed elements - •SHOULD use
size-*for square elements instead ofw-*+h-*
Detected Layout Patterns
- •Main Content: width: 1920px, height: 1016px
- •Header: height: 64px
- •Main Content: width: 1920px, height: 608px
- •Main Content: width: 1920px, height: 1001px
- •Header: height: 63px
Components
Buttons
| Variant | Background | Text | Border | Height | Radius |
|---|---|---|---|---|---|
| Ghost | transparent | #497009 | none | - | - |
Interactive States
Focus
- •MUST use
2pxoutline with accent color (#B7DF2F) - •MUST use
2pxoutline-offset - •NEVER remove focus indicators
Hover
- •Buttons (primary): lighten background by 10%
- •Buttons (secondary): use
#C3FE09background - •List items: use
#C3FE09background
Disabled
- •MUST use
opacity: 0.5 - •MUST use
cursor: not-allowed
Interaction
- •MUST use an
AlertDialogfor destructive or irreversible actions - •SHOULD use structural skeletons for loading states
- •MUST show errors next to where the action happens
- •NEVER block paste in
inputortextareaelements - •MUST add an
aria-labelto icon-only buttons
Animation
- •NEVER add animation unless it is explicitly requested
- •MUST animate only compositor props (
transform,opacity) - •NEVER animate layout properties (
width,height,top,left,margin,padding) - •SHOULD use
ease-outon entrance animations - •NEVER exceed
200msfor interaction feedback - •SHOULD respect
prefers-reduced-motion
Performance
- •NEVER animate large
blur()orbackdrop-filtersurfaces - •NEVER apply
will-changeoutside an active animation - •NEVER use
useEffectfor anything that can be expressed as render logic
