Color Harmony: Split-Complementary Scheme
The Clean 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
Clean technology companies (solar, wind, battery storage) adopted dual blue-green systems to simultaneously signal sky/wind energy (blue) and land/biomass energy (green).
Best Design Use Cases
White for all surfaces. Sky blue for primary elements. Emerald for secondary and growth indicators. Dark for text.
Industries This Palette Suits
Clean energy, climate tech, solar power, wind energy, battery storage.
Colors That Pair Well With Clean 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.
orange
directly opposite #0EA5E9 on the wheel — the strongest accent for CTAs and highlights when you need maximum energy
blue
30° beside #0EA5E9 — 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 Clean Tech Without Breaking Accessibility
- Avoid #0EA5E9 for small UI elements on #FFFFFF — at 2.8:1 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.
- Let #10B981 carry sidebars, cards and footers — at a mid lightness it separates zones without stealing focus from #0EA5E9.
How to Implement the Clean Tech Color Scheme
To use this Clean Tech color palette in your web project, you can copy the following CSS variables or Tailwind CSS configuration. These roles ensure your UI maintains accessibility and visual hierarchy.
Option 1: CSS Variables
:root {

'} --color-bg: {colors[0]};{'
'} --color-primary: {colors[1]};{'
'} --color-secondary: {colors[2]};{'

'} {'}'}Web Design Tip
Use #FFFFFF for the main background and #0EA5E9 for primary buttons. This creates a high-contrast focal point.
Accessibility Note
The contrast ratio between #1A1A1A and #FFFFFF is 17.40:1 (AAA). Ensure your body text remains legible.
