Color Format Converter Calculator

Use this color converter to translate common screen color values between HEX, RGB, and HSL. It is useful for CSS, UI design, brand handoffs, design tokens, and checking whether two tools are describing the same color.

How to use this calculator

Choose an Input format. In RGB or HEX channels mode, enter red, green, and blue channel values from 0 to 255. In HSL mode, enter hue in degrees plus saturation and lightness percentages. The result shows the HEX value, the matching RGB string, the matching HSL string, and each channel.

How it works

RGB stores red, green, and blue intensity as whole channels. HEX is the same channel data written in base 16, usually as six digits. HSL describes hue angle, saturation, and lightness, which is often easier when adjusting a color lighter, darker, or less saturated.

For example, RGB 255, 0, 0 converts to HEX FF0000 and HSL 0°, 100%, 50%. For other web calculations, see the binary to hexadecimal calculator, percentage calculator, and ppi calculator.

Design tips

Use the converted value as a starting point, then check contrast in the actual interface. Do not rely on color alone for errors or success states, and remember that this form does not model printer profiles or opacity.
