Color Harmony: Split-Complementary Scheme
The Supabase palette is built using a split-complementary relationship between its hues. This ensures that even with high-contrast accents, the overall scheme feels balanced and intentional.
Hue Wheel
A split-complementary palette is often preferred by professional designers because it balances visual interest with cohesion.
History & Design Context
Supabase launched in 2020 as an open-source Firebase alternative. The green was chosen deliberately to differentiate from Firebase's orange and signal both freshness and connection to open-source culture.
Best Design Use Cases
Dark charcoal for all surfaces. Bright green for brand moments and primary interactive elements. White for content. Gray for metadata.
Industries This Palette Suits
Backend infrastructure, developer tools, database products, open source.
Colors That Pair Well With Supabase
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.
rose-red
directly opposite #3FCF8E on the wheel — the strongest accent for CTAs and highlights when you need maximum energy
teal
30° beside #3FCF8E — a calm secondary that extends the palette without adding tension
tinted neutral
a paper-white carrying the palette's own hue — perfect for surfaces and dividers
Using Supabase Without Breaking Accessibility
- Use #3FCF8E for buttons and links — it scores 8.5:1 against the #1C1C1C background (above the 3:1 UI-components threshold).
- Set body text in #888888 — 4.8:1 against #1C1C1C passes WCAG AA (AA) 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.
