Color Harmonies

Six established ways to build a palette around #91EB33. Click any swatch to copy its value, or open it to see the full breakdown.

Complementary

The colour directly opposite on the wheel.

#91EB33 This color

#8C33EB

Use it when: Highest possible contrast between two hues. Use it when one element has to stand out against everything else: a call-to-action button, a highlight, a single focal point.
Watch out: Side by side at full saturation the edges appear to vibrate. Give one colour far less area than the other, or take saturation out of one of them.

Split-complementary

Instead of the opposite colour, the two next to it.

#91EB33 This color

#3336EB

#E833EB

Use it when: Almost the contrast of a complementary pair, but noticeably calmer. A good default when complementary feels too harsh: one dominant colour, two accents.
Watch out: The two accents are close to each other. Keep them apart in the layout, or one will read as a mistake.

Analogous

Direct neighbours on the wheel.

#EBE833

#91EB33 This color

#36EB33

Use it when: Naturally harmonious because the colours share undertones. Works well for backgrounds, gradients and calm interfaces where nothing should shout.
Watch out: Contrast between them is low. Do not rely on hue alone to separate interactive elements - vary lightness as well.

Triadic

Three hues at equal distance, 120 degrees apart.

#91EB33 This color

#3392EB

#EB3392

Use it when: Vivid and balanced at the same time. Suits playful, illustrative work and anything that needs three clearly distinct categories.
Watch out: Three strong colours are hard to balance. Let one dominate and treat the other two as accents, otherwise the result looks restless.

Tetradic

Four hues forming two complementary pairs.

#91EB33 This color

#33EBE8

#8C33EB

#EB3336

Use it when: The richest of the classic schemes. Useful when a design genuinely needs four distinct colours, for example a chart with four series.
Watch out: The hardest scheme to control. Choose one lead colour, use the rest sparingly, and watch the balance between warm and cool.

Monochromatic

One hue, stepped through lightness.

#44790C

#6BBE13

#92EB33

#B7F278

#DCF9BE

Use it when: Always coherent, because there is only one hue. The natural choice for interface hierarchies, single-series charts and restrained designs.
Watch out: Can read as flat. Add one neutral or a single accent colour wherever something needs to be noticed.

Using this color

The same colour behaves very differently depending on where it sits. The mockups show it leading a design; the cards below state contrast ratios, so you can see at a glance what holds up.

A second surface, drawn from the same palette.

Gradients between neighbouring hues stay clean. Across the wheel they pass through a muddy middle - keep those short.

#91EB33 leads; the supporting tones are taken from its own scale, so what you see is one colour doing the whole job.
