Random Color Generator

The Random Color Generator invents fresh colours on demand and shows each one as a hex code, an rgb() string and an hsl() string.

It is the fastest way to break a creative block: when you cannot decide on a background, a button colour or a chart palette, generate a batch of swatches and let an unexpected combination spark an idea.

Designers, front-end developers, illustrators and anyone choosing a theme can use it to explore the full colour space without endlessly nudging sliders.

Choose how many colours you want — anything from a single pick to a grid of one hundred — then press Generate.

Each swatch is rendered as a real colour tile so you can judge it at a glance, with its hex value beside a copy button and its rgb() value underneath.

A Copy all button grabs every hex code as a newline-separated list, handy for pasting straight into CSS, a design token file or a spreadsheet.

The colours are drawn from the browser’s Web Crypto random source, so the distribution is even across the spectrum rather than biased toward any particular hue.

Like every My Tools Garage tool it runs entirely in your browser.

Nothing is uploaded or tracked, generation is instant, and it keeps working offline once the page has loaded, so you can brainstorm palettes anywhere.
