Color Converter

A color converter translates a color between representations used by CSS, design tools, and APIs. HEX expresses channel bytes, RGB expresses red, green, and blue values, and HSL separates hue, saturation, and lightness for human-oriented adjustments. Alpha may be represented separately or included in a modern notation. Conversion changes the notation, not the visual intent, but rounding can create small differences.

Validate the input syntax and channel ranges before copying a value into a stylesheet or design token. Distinguish a three-digit shorthand from a full six-digit HEX value, preserve alpha when it is meaningful, and verify whether the target uses percentages or byte values. For accessible UI, check contrast in the final rendering rather than trusting a color label. Color conversion is not the same as color management across display profiles.

Color values are local design data and do not require a network request to convert. Immediate browser feedback makes it easier to compare a token with a screenshot, adjust a theme, or prepare a CSS variable without sending a project palette to a service. The resulting value still needs review in context: contrast, dark-mode behavior, transparency over backgrounds, and the target browser's supported syntax determine whether a color is usable.
