Color Harmony: Analogous Scheme
The Rhea Crater 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
Rhea, discovered by Cassini in 1672, is a mostly water-ice world with a thin oxygen atmosphere discovered in 2010, the first oxygen atmosphere found on a moon other than earths.
Best Design Use Cases
Use the crater white for the surface, ice shadow for the pits, pale grey for highlights, and dark slate for text.
Industries This Palette Suits
Space science, astronomy, education, exploration.
Colors That Pair Well With Rhea Crater
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.
yellow
directly opposite #8E8E9E on the wheel — the strongest accent for CTAs and highlights when you need maximum energy
violet
30° beside #8E8E9E — 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 Rhea Crater Without Breaking Accessibility
- Avoid #8E8E9E for small UI elements on #C8C8D0 — at 1.9:1 it misses the 3:1 WCAG threshold; darken it with a shade from the ramp below.
- Set body text in #2E2E3A — 8.1:1 against #C8C8D0 passes WCAG AA (AAA) for long-form reading.
- Don't use #E8E8F0 behind body text — this light tone works better for surfaces, badges and dividers than for reading areas.
