Color Harmony: Analogous Scheme
The Y Combinator palette is built using a analogous relationship between its hues. This ensures that even with high-contrast accents, the overall scheme feels balanced and intentional.
Hue Wheel
A analogous palette is often preferred by professional designers because it creates a calm, serene atmosphere by using neighboring colors.
History & Design Context
Y Combinator has used this orange since its founding in 2005. Paul Graham designed the original visual identity. The orange has become shorthand for 'funded and validated.'
Best Design Use Cases
White for all content. Orange exclusively for the logo, Hacker News UI, and primary brand moments. Dark for all text. The orange must be used sparingly.
Industries This Palette Suits
Venture capital, startup ecosystem, tech media, incubators, founders.
Colors That Pair Well With Y Combinator
Need a fifth color? These three companions are computed from the palette's own hue positions on the color wheel, so they extend the scheme without breaking its harmony.
cyan-blue
directly opposite #FF6600 on the wheel — the strongest accent for CTAs and highlights when you need maximum energy
yellow
30° beside #FF6600 — a calm secondary that extends the palette without adding tension
tinted neutral
a ink-black carrying the palette's own hue — perfect for surfaces and dividers
Using Y Combinator Without Breaking Accessibility
- Avoid #FF6600 for small UI elements on #FFFFFF — at 2.9:1 it misses the 3:1 WCAG threshold; darken it with a shade from the ramp below.
- Set body text in #1A1A1A — 17.4:1 against #FFFFFF passes WCAG AA (AAA) for long-form reading.
- Don't use #FFFFFF behind body text — this light tone works better for surfaces, badges and dividers than for reading areas.
How to Implement the Y Combinator Color Scheme
