Color Scheme Generator

Color harmony is the principle that certain combinations of hues are naturally pleasing to the eye because of their geometric relationship on the color wheel. Every mode this generator offers is based on a different type of relationship — and each produces a distinctly different feel. Understanding what each mode does helps you choose the right starting point rather than generating repeatedly until something clicks.

Complementary and Split-Complementary

Complementary colors sit directly opposite each other on the color wheel — blue and orange, red and green, purple and yellow. This opposition creates the highest possible contrast between two hues, which is why complementary schemes feel bold and energetic. Used in equal proportions, they can feel jarring; used with one dominant and one accent, they create strong visual focus. Split-complementary softens this by replacing the direct complement with the two colors flanking it — so instead of blue opposite orange, you get blue with yellow-orange and red-orange. The contrast is still present but the scheme is more forgiving and easier to balance across a design.

Both modes work well for designs that need visual energy — marketing materials, product packaging, interactive interfaces, and any context where you want elements to stand out against each other.

Analogous and Monochromatic

Analogous schemes pull from a narrow arc of the color wheel — neighboring hues that share an underlying tone. Because the hues are close together, the scheme feels cohesive and calm. There's no tension between competing colors, which makes analogous palettes easy to apply broadly across a layout without any element fighting for attention. The trade-off is that analogous schemes can feel flat without deliberate variation in lightness and saturation. This generator compensates by varying the lightness across each swatch, ensuring some contrast even within the narrow hue range.

Monochromatic takes this further — all swatches share the same hue, distinguished only by their lightness and saturation. Monochromatic schemes are the most cohesive option, with no hue variation at all, and they work exceptionally well for minimalist designs, editorial layouts, and anything where tone and texture matter more than color variety.

Triadic Schemes

A triadic scheme uses three hues evenly spaced around the color wheel — 120 degrees apart. This creates a scheme with variety and balance simultaneously. Unlike complementary schemes, which create a dominant axis of contrast, triadic schemes distribute visual interest across three poles. The result feels lively and well-rounded without the tension of a complementary pair. When working with a triadic palette, it's usually most effective to let one hue lead and use the other two in supporting roles — otherwise the balance can read as busy rather than vibrant.

Using the Lock System

Once you find a color you want to keep, hover over its swatch and click the lock icon in the top right corner. Locked colors stay in place when you regenerate, so you can fix a hue you love and let the generator find new companions for it. This is especially useful when a client has an existing brand color that must appear in the final palette — lock it, then regenerate until the rest of the scheme feels right. You can lock any number of swatches, including all of them to preserve the full palette while changing the count.
