What is a gerador de cores aleatórias?

gerador de cores aleatórias creates fresh digital colors for design, code and creative work. It rolls independent HEX colors, converts each one to RGB and HSL, recommends readable black or white text, and lets you lock favorites before rerolling the rest. Everything runs in your browser.

Como usar

1Choose how many colors to roll. Use the color count control for anything from a single random color to a lightweight set of twelve.
2Reroll or change the seed. Click the reroll button for a fresh seed, or type your own seed to recreate the same random colors later.
3Lock favorites and copy output. Lock any swatch you want to keep, reroll the others, then copy a single format, the HEX list, CSS variables or a quick gradient.

Para quem é

Perguntas frequentes

Is this gerador de cores aleatórias free?

Yes. It is free, has no sign-up and has no usage limit. Generate one color or a small set whenever you need quick CSS-ready values.

Are my colors uploaded anywhere?

No. The colors, seed and locks stay in your browser. The generator uses local JavaScript and does not send your color choices to a server.

What color formats can I copy?

Each random color includes HEX, RGB and HSL. You can also copy the whole set as a HEX list, CSS custom properties or a linear-gradient string for quick experiments.

What does the seed do?

The seed turns the random roll into a repeatable result. Use the same seed and color count to get the same color set again.

How is readable text chosen?

The tool compares each background color against black and white using the WCAG contrast ratio formula. It recommends the text color with the higher contrast.

Is this a color palette generator?

It is related, but the job is different. This page generates independent random colors. Use the color palette generator for coordinated harmonies.
