How to use this calculator
Each channel is independently randomised. HSL is converted from RGB: H = hue (0°–360°), S = saturation (%), L = lightness (%).
- 1
Set the number of colors to generate (up to 10).
- 2
Choose a style: any, bright, pastel, dark, or light.
- 3
Set a seed number to reproduce the same set of colors later.
Frequently asked questions
How do I use hex colors in CSS?
Use the hex code directly: color: #FF5733; or background-color: #FF5733;. Hex codes are the most widely supported color format in CSS and HTML.
What is the difference between RGB and HSL?
RGB describes color as amounts of Red, Green, Blue (0–255 each). HSL describes color as Hue (0°–360°, the color wheel position), Saturation (0–100%, colour intensity), and Lightness (0–100%, darkness to brightness). HSL is more intuitive for making colors lighter or more saturated.
What is a seed in random generation?
A seed is a starting number for the random algorithm. The same seed always produces the same sequence of "random" numbers — useful when you want to reproduce a color set you liked. Leave it at 0 for a truly random result each time.
Random Color Generator — HEX, RGB & HSL
Using random colors in design
Random color generators are useful for prototyping, mood boards, and finding unexpected combinations. For production use, pair this tool with a color palette generator to ensure contrast ratios meet WCAG accessibility standards (minimum 4.5:1 for normal text).
Pastel vs bright vs dark palettes
Pastel colors (high lightness, low saturation) are popular for soft UI, wellness, and baby products. Bright/vivid colors create high impact for tech, gaming, and youth brands. Dark palettes suit luxury, nightlife, and developer tools. Matching your color palette to your brand personality is more important than individual color choice.
