  • Use it for the primary call to action and nothing else.
  • Check the pairing at small sizes on a neutral background.

Avoid

  • Do not place it beside clashing neon greens or electric blues.
  • Never use it for long body text on white.
  • Avoid gradients that shift its hue into another family.

Can three steps of one hue work together

Three steps from the 50–950 scale of “Vivid Indigo”: same hue, only lightness differs. Below is the contrast whenever one of them is text on another.

200#DFCCFF
500#9474DC
800#4E347F
  • 200 ↔ 500: 2.46:1 (FAIL)
  • 500 ↔ 800: 2.73:1 (FAIL)
  • 200 ↔ 800: 6.70:1 (AA)

Pairs reaching 4.5:1 (AA body text): 1 of 3. Pairs reaching 3:1 (large text, icons, borders): 1 of 3. The rest fall below 3:1 and should not carry text.

Color combinations

Rotate the hue wheel while holding lightness steady.

How to use it

Three moves keep the color readable and deliberate.

Why it works

The perceptual reasoning behind the palette.

All six palettes rotate hue at similar lightness, so the best in-group contrast falls between 1.02:1 and 1.94:1. Use them for fills, charts and graphics rather than as text on each other — when you need text, use a neutral or a darker step of the same scale.

Complementary

Opposite the hue wheel; it sharpens the focal color by contrast.

#6441A4#576200

Best use: Calls to action and single-feature highlights

Split-complementary

Two neighbors of the opposite hue; softer than a direct complement.

#6441A4#7F4F00#006F19

Best use: Balanced marketing layouts with two accents

Triadic

Three hues spaced evenly; lively but needs one dominant voice.

#6441A4#963A00#007357

Best use: Event identities and playful editorial spreads

Analogous

Neighbors on the wheel; quiet, cohesive and easy to scan.

#3251AE#6441A4#833386

Best use: Backgrounds, charts and calm product pages

Monochromatic

One hue across lightness steps; disciplined and premium.

#482F76#6441A4#8F76BD

Best use: Design systems, packaging and typographic hierarchy

Tetradic

Two complementary pairs; rich, but requires strict proportion.

#6441A4#97285C#576200#007357

Best use: Complex dashboards and multi-service brands
