Frequently Asked Questions
Does this tool show HSL values?
No — only HEX and RGB values are shown. There's no HSL, CMYK, or other color-format output.
Can I "lock" a color while generating others?
Not exactly — there's no lock toggle. But in Palette mode, clicking any of the 5 generated swatches makes that color the main displayed one, so you can keep coming back to a color you like while regenerating the rest of the palette.
Does the palette use color harmony rules like complementary or analogous?
No. The 5 palette colors are each fully random and independent — there's no complementary, analogous, triadic, or monochromatic mode.
Can I filter for warm, cool, pastel, or accessible colors?
No — there are no color-type filters. Every generated color is a uniformly random RGB value with no constraints on hue, saturation, contrast, or accessibility.
Can I save or export my generated colors?
No — there's no save, favorites, or export feature. Copy the HEX or RGB value you want before generating a new color, since nothing is stored.
Is my data safe when using the Random Color Generator?
Completely safe. The Random Color Generator processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.
Are the results from the Random Color Generator truly random?
Yes. The Random Color Generator uses your browser's standard random number generator (JavaScript's Math.random()), which is suitable for games, decisions, and everyday randomness. It is not a cryptographically secure generator — for security-sensitive use cases like generating passwords or cryptographic keys, use a tool built specifically for that purpose.
Can I customise what the Random Color Generator generates?
Yes. Where customisation options are available, you can add your own items, set numeric ranges, or adjust parameters before generating. Default settings are designed for the most common use case so you can get an instant result without any configuration.
