Frequently Asked Questions

Is my data sent to a server?
No. All colour conversions happen locally using JavaScript in your browser. No colour values or any other data are ever sent to a server.
What is a HEX colour code?
A HEX (hexadecimal) colour code represents a colour as three two-digit base-16 numbers for red, green, and blue channels, written after a # symbol — for example #3a7bd5. Values range from 00 (0 in decimal) to ff (255 in decimal) per channel.
What is RGB?
RGB describes a colour using three decimal numbers for its red, green, and blue channels, each between 0 and 255. For example, rgb(58, 123, 213) is the RGB equivalent of #3a7bd5.
What is HSL?
HSL stands for Hue, Saturation, and Lightness. Hue is a degree on the colour wheel (0–360°), Saturation is how vivid the colour is (0–100%), and Lightness is how light or dark it is (0–100%). HSL is often more intuitive than RGB or HEX for designers tweaking colours in CSS.
How do I convert HEX to RGB?
Each pair of hex digits maps to one RGB channel. #3a7bd5 breaks into 3a → red = 58, 7b → green = 123, and d5 → blue = 213. This tool does the conversion instantly — just type your HEX value in the HEX tab.
Can I use this to get CSS colour values?
Yes. For each format the tool shows both the plain colour value and the CSS-ready string (e.g. color: #3a7bd5; or color: rgb(58, 123, 213);). Click either row to copy it straight to your clipboard.
