Generate random HEX colors for design experiments and sample data. Build a palette of independent colors without manual color picking.
How to use
Choose how many colors to generate and run the tool. Copy individual HEX values into your design or CSS, then check them together.
Example
Generate three colors for a mockup and assign them to sample chart series. Test each against the chart background.
FAQ
Are the colors accessible or harmonious?
Not automatically. Random selection does not evaluate contrast, color blindness, or visual harmony. Check contrast before using text colors.

A practical task
Assign random colors to sample data before deciding if they suit a design. A palette for adjacent chart bars needs distinguishable colors, while text colors also need contrast against the background. Those are separate checks from generating valid HEX values.
Another useful question
Can I generate matching brand colors automatically?
Random selection does not follow your brand palette or a harmony rule. Keep colors that meet the design constraints and adjust the rest deliberately.

Details for interpreting the result
| Detail | Explanation |
|---|---|
| RGB channels | RGB describes red, green, and blue light channels. In the common integer form, each runs from 0 through 255. A six digit HEX value represents the same three channels as two hexadecimal digits per channel. |
| HSL values | HSL separates hue, saturation, and lightness. It is useful for describing variations of one color, but the lightness percentage is not a direct measure of perceived contrast or accessibility. |
| Color contrast | A foreground and background need enough contrast for readable text. Attractive colors do not automatically produce accessible combinations. Check the intended font size, text weight, and actual background together. |
| Rounded color components | Rounding hue, saturation, or lightness removes some numeric precision. Keep the original RGB channels or HEX value when comparing an exact brand color. A visually similar rounded result is not proof of exact channel equality. |
| Supported color notation | A converter only understands the input notations it implements. A valid color in CSS can still use syntax outside that set. Check alpha channels, named colors, and newer CSS color forms before treating an input rejection as an invalid color. |
| The display context | A color sample appears beside other colors and under display settings that affect perception. Evaluate the chosen value in the actual interface with its neighbors and text, rather than approving an isolated square alone. |
