Random Hex Color Generator
Generate one or more random hex color codes instantly. Great for design inspiration. Free, no signup.
How to use this tool
- Choose how many colors to generate.
- Click Calculate to get a fresh palette.
- Copy any hex code and paste it directly into your CSS or design tool.
- Click again to generate a completely new set.
Instantly generate random hex color codes for use in CSS, design mockups, data visualisations, or creative projects. Each color is a 6-digit hex value like #a3f2c1.
How it works
The Random Hex Color Generator produces one or more six-digit hexadecimal color codes in the format #RRGGBB. Each color is chosen by randomly selecting three values (red, green, blue) from 0 to 255 and encoding each as a two-digit hex pair. The result is a valid CSS color that can be used directly in web design, graphic tools, or code.
Use it when you need a quick color palette starting point, a random accent color for a design mockup, or a color-coding scheme for data visualization where you have no specific brand constraint. Generate multiple colors at once to build a palette and then refine the ones that appeal visually.
Because the generator samples the full RGB color space uniformly, expect a wide variety including very dark, very light, and highly saturated colors. If you need colors within a specific hue or lightness range, copy promising hex codes into a color picker and adjust from there.
Worked example
Building a 5-color inspiration palette
- Set Number of colors to 5.
- Click Generate.
- Review the five hex codes and their color swatches.
- Copy any codes you like into your design tool (Figma, CSS file, etc.).
- Regenerate for a fresh set if the palette does not suit your project.

Common mistakes to avoid
- Using a randomly generated color directly on text without checking contrast ratios against the background -- low-contrast text fails accessibility standards.
- Generating only one color when you need a palette -- multiple colors give you combinations to work with from the start.
- Forgetting the # prefix when pasting hex codes into systems that require it (most CSS and design tools need the # included).
Key terms
- Hex color code
- A six-character string prefixed with # representing a color as three two-digit hexadecimal values for red, green, and blue channels.
- RGB

Frequently asked questions
- What is a hex color code?
- A hex color is a 6-digit hexadecimal number representing the red, green, and blue channels of a color (e.g. #ff5733 = R:255 G:87 B:51).
- Can I get colors in a specific hue range?
- This tool generates fully random colors. For hue-limited palettes use a dedicated color palette generator.
