Color Palette Generator (Monochromatic, Analogous, Triadic)

Five swatches built from one base color's hue

Starting from base color #3B82F6 with an analogous scheme, the generator produces 5 swatches: #3bdff6, #3bb1f6, #3b82f6 (the original base, centered in the sequence), #3b53f6, and #523bf6.

An analogous color scheme works by rotating hue in small steps on either side of the base color while keeping saturation and lightness constant -- notice the green (3b) and blue (f6) channel values barely shift across most of these swatches, while the middle channel (which encodes hue rotation in this blue-dominant range) shifts steadily, producing a smooth, closely related family of colors rather than dramatically different ones.

This scheme type is popular specifically because analogous colors, being close together on the color wheel, are naturally harmonious when used together -- unlike complementary or triadic schemes (opposite or evenly-spaced hues), which produce more visual contrast and tension by design.

What this generator does, and what it leaves to other tools

Hue rotation in HSL. Print conversion and brand libraries are separate. This works by converting the base color to HSL (hue, saturation, lightness), rotating the hue value by fixed steps, and converting each result back to hex -- a mathematically clean approach that keeps saturation and lightness consistent across the whole palette, which is what gives an analogous scheme its cohesive look.

This produces screen-ready hex colors only -- if the palette needs to be converted for print production (CMYK), that's a separate conversion step this tool doesn't perform, since RGB/hex and CMYK don't have a perfect one-to-one mapping.

This generates a palette from pure color theory (hue relationships), not from any existing brand guideline or established color library -- if you're trying to match a specific brand's official palette, cross-reference against that brand's own published color values rather than relying on generated analogous colors alone.

Related color and palette tools

For lighter and darker variations of a single color (rather than hue-shifted analogous colors), the Color Shade & Tint Generator is the complementary tool.

Once you have a palette, checking it for accessibility and colorblind-safety is a worthwhile next step -- the Color Blindness Simulator and Colorblind-Safe Palette Suggester cover that.
