How to Pick Random Colors for Design Ideas
Random colors break palette blocks and speed up mockups. This guide explains hex and RGB forms and how to turn a random pick into a usable palette.
What is the Random Color Generator?
Random colors spark ideas when a palette feels stuck or a mockup needs a quick fill. Each run picks a new red, green and blue value at random and shows the matching hex and RGB forms. Run it a few times, note any color you like, and build from there.
How to use it
- Choose whether you want hex, RGB or both.
- Click Generate random color.
- Copy a color you like before running it again.
Worked example
With the hex + rgb format, each run shows one random color as a six-digit hex value plus its matching rgb() value, for example in the form Hex: #a1b2c3 and RGB: rgb(161, 178, 195). The exact values are random, so every run differs.
Should I use a random color as-is?
Treat it as a starting point. Check it against your text for contrast, then adjust lightness or pair it with neutrals before using it in a finished design.
Frequently asked questions
Are the colors truly random?
They come from the built-in random number source on your device, which is random enough for palettes, mockups and inspiration, though not for security uses.
How do I use a hex value in CSS?
Paste it wherever a color belongs, such as color: #a1b2c3 or background: #a1b2c3, and it will render as that color.
