Color Converter

Different color models exist because different mediums represent color differently. Screens use additive mixing (RGB), where combining red, green, and blue light at full intensity produces white. Printers use subtractive mixing (CMYK), where layering cyan, magenta, yellow, and black inks absorbs light to produce darker colours. HSL and HSV describe colour in terms that align with how humans perceive hue, saturation, and brightness, making them intuitive for design workflows.

HEX notation is shorthand for RGB values encoded in hexadecimal and is the most common format in CSS. Converting between these models is a straightforward mathematical transformation, and this tool performs all conversions in real time as you edit any field. The contrast ratio section evaluates readability against WCAG accessibility guidelines, helping you choose colours that work for all users.
