About this tool: Color Palette Generator
Choose a base color and harmony mode to create a deterministic palette, preview swatches and copy individual HEX values or the full palette.
The output is meant to support practical visual decisions such as dimensions, color choices, contrast or layout planning.
Color Palette Generator is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
The base color is converted to HSL. Analogous and triadic modes shift hue angles, complementary mode includes the opposite hue, and monochromatic mode varies lightness while keeping the hue family.
Practical example
Using #3157D5 in complementary mode creates a palette that includes the base blue and a hue approximately 180° opposite it.
