Color Harmonies

Six established ways to build a palette around #52B2BF. Click any swatch to copy its value, or open it to see the full breakdown.

Complementary

The colour directly opposite on the wheel.

#52B2BF This color
#C06054
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.

#52B2BF This color
#C0547D
#C09654
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.

#54C096
#52B2BF This color
#547DC0
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.

#52B2BF This color
#C054B3
#B3C054
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.

#52B2BF This color
#9654C0
#C06054
#7DC054
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.

#215359
#368791
#54B3C0
#8CCCD4
#C3E5E9
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.

Badge Outline

In a gradient

with its neighbour
with its complement

Neighbouring hues blend smoothly. Complements pass through a muddy middle, so keep that gradient short or add a stop.

How others see this colour

Around one in twelve men and one in two hundred women perceive colour differently. Two shades that look distinct to most people can collapse into one for them - which is why meaning should never rest on colour alone.
