Color Harmony: Split-Complementary Scheme
The Climate Tech 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
Climate technology companies face a visual communication challenge: conveying both urgency and hope. The dark-and-bright approach emerged as the solution in the 2020s.
Best Design Use Cases
Dark blue-black for surfaces. Electric green for growth and solution metrics. Bright blue for climate data and earth references. White for all content.
Industries This Palette Suits
Climate technology, clean energy, carbon capture, sustainability platforms, ESG tools.
Colors That Pair Well With Climate Tech
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 #00C896 on the wheel — the strongest accent for CTAs and highlights when you need maximum energy
cyan-blue
30° beside #00C896 — 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 Climate Tech Without Breaking Accessibility
- Use #00C896 for buttons and links — it scores 7.8:1 against the #0D1F2D background (above the 3:1 UI-components threshold).
- Set body text in #FFFFFF — 16.8:1 against #0D1F2D passes WCAG AA (AAA) for long-form reading.
- Don't use #4AB8D8 behind body text — this light tone works better for surfaces, badges and dividers than for reading areas.
