Understanding Color Formats
- HEX (Hexadecimal)The standard for web CSS color definition. It uses six digits (0-9, A-F) to represent Red, Green, and Blue. Example:
#FFFFFFfor White. - RGB (Red Green Blue)Used by screens to create colors by mixing light. Values range from 0 to 255. Ideal for Javascript manipulations and Canvas APIs.
- HSL (Hue Saturation Lightness)The most intuitive format for humans.Hue is the color type (0-360°),Saturation is intensity, andLightness is brightness. Learn more on Wikipedia.
Why Use Toolk Converter?
Unlike basic tools, you can edit RGB or HSL inputs directly. Changing the "Red" value updates the HEX code instantly.
Get accurate CMYK values for your print projects. We use standard color profile algorithms to ensure your blacks (K) and colors match as closely as possible.

Frequently Asked Questions (FAQ)
How precise is the conversion?
Our converters use floating-point math for HSL/CMYK to ensure high precision, though we display rounded values for standard CSS usage. The conversions between HEX and RGB are exact and lossless.
Why does the HEX code change when I edit HSL?
This happens because the HEX model has a limited gamut compared to floating-point HSL. When you adjust lightness or saturation minutely, it snaps to the nearest available 24-bit RGB/HEX color.
