Color Palette Generator
Generate complementary, analogous and triadic palettes from one colour.
Turn one brand colour into a complete, usable UI palette.
The palette appears here
The Brand Palette Generator turns one brand colour into an entire interface palette: a primary ramp, neutrals tinted with your hue, a harmonious secondary, and semantic success, warning, error and info colours adjusted to sit with the rest.
A brand colour is not a palette. Shipping an interface needs neutrals for text and surfaces, a secondary colour for the things that are not the main action, and semantic colours for success, warning, error and information — and all of them have to look like they belong to the same product.
This builds the whole set from one colour. The primary ramp comes from your colour directly. The neutrals are derived from it rather than being generic greys — they carry a trace of your hue, which is what makes a palette feel considered rather than assembled. The secondary is placed at a harmonious angle, and the semantics are anchored to the hues people expect while being pulled toward your brand's saturation and lightness so they do not look borrowed from elsewhere.
Every colour arrives as a full scale rather than a single value, every scale is checked for contrast, and the whole thing exports as CSS custom properties, Tailwind tokens or design tokens in JSON — with a dark mode variant generated alongside.
Greys carrying a trace of your hue, which is the difference between a palette that feels considered and one that feels assembled.
Success, warning, error and info stay recognisable but are pulled to your brand’s saturation and lightness.
Every role arrives as a full ramp, because an interface needs hover states and borders as well as a base colour.
A matching dark theme generated alongside, with surfaces and accents adjusted rather than inverted.
CSS custom properties, Tailwind tokens or W3C design tokens in JSON.
The one thing you already know. Everything else is derived from it.
How much of your hue the greys should carry, from pure neutral to clearly tinted.
Success, warning, error and info, adjusted to sit with your brand rather than against it.
CSS variables, Tailwind tokens or design tokens, with dark mode included.
Because a pure neutral grey next to a warm brand colour reads as slightly wrong — people notice it without being able to name it. A few percent of your hue in the greys ties the whole interface together.
Yes, and you should keep them recognisable — green for success, red for error, amber for warning. What the tool adjusts is their saturation and lightness so they sit at the same intensity as the rest of your palette.
A primary, a neutral ramp, and four semantics is enough to build almost anything. A secondary is a nice-to-have. Palettes fail from having too many colours far more often than too few.
It is a good starting point. Dark themes need surfaces to be near-black rather than inverted white, and saturated colours usually need pulling back, which the generator does — but the result still deserves a designer’s eye before it ships.
