Color Harmony: Analogous Scheme
The Iolite 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.
A analogous palette is often preferred by professional designers because it creates a calm, serene atmosphere by using neighboring colors.

Colors That Pair Well With Iolite
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.
directly opposite #3B4A92 on the wheel — the strongest accent for CTAs and highlights when you need maximum energy
30° beside #3B4A92 — a calm secondary that extends the palette without adding tension
a ink-black carrying the palette's own hue — perfect for surfaces and dividers
Using Iolite Without Breaking Accessibility
- Use #3B4A92 for buttons and links — it scores 6.5:1 against the #E4E6E8 background (above the 3:1 UI-components threshold).
- Set body text in #0A0F30 — 14.9:1 against #E4E6E8 passes WCAG AA (AAA) for long-form reading.
- Let #232E6C carry sidebars, cards and footers — at a mid lightness it separates zones without stealing focus from #3B4A92.
