Color Name
Find the nearest CSS named color for any HEX or RGB value.
The Color Name tool finds the nearest CSS named colour for any HEX or RGB value you enter. It is a handy way to get a readable name for a colour you are working with.
What is a Color Name Converter?
A color name converter is a tool that identifies the closest CSS named color for any given HEX or RGB color value. It uses a lookup table of 148 standard CSS color names and calculates the Euclidean distance in RGB space to determine the nearest match. This helps designers and developers quickly find standardized color names for arbitrary color codes they encounter in design tools or real-world applications, making it easier to communicate color specifications using familiar names like Royal Blue, Forest Green, or Crimson instead of cryptic hexadecimal codes.
Understanding CSS color names is valuable when working with legacy CSS codebases, educational resources, or design systems that favor named colors for their readability and memorability. The converter bridges the gap between precise numeric color definitions and the more accessible human-readable color names. This tool runs entirely in your browser without sending any data over the network, ensuring complete privacy for your color explorations. You can input either a HEX value starting with a hash symbol or an RGB triplet separated by commas and obtain the closest named color match instantly.
The embedded CSS color table contains all 148 standard CSS color names with their exact hexadecimal and RGB values. When you enter a color, the algorithm computes the distance between your input's red, green, and blue components and each named color's components, finding the smallest overall difference. This provides an accurate approximation of the visual similarity between colors. Additionally, you can reverse the process by selecting any color name from the dropdown menu to instantly see its precise HEX, RGB, and HSL representations for direct copying or further use in your projects.
How to use this Color Name Converter
- Enter a HEX color starting with # (e.g., #3a6ea5) to find the nearest CSS named color.
- Enter an RGB value as three comma-separated numbers (e.g., 58,110,165) to identify the closest named color.
- View the exact HEX, RGB, and HSL values of both your input and the closest named color.
- Select any color name from the dropdown list to instantly see its HEX, RGB, and HSL values.
- Click any result value to copy it to your clipboard for immediate use in your code.
