Color Picker & Converter FAQs

All three represent the exact same sRGB color space in browsers: #HEX encodes Red, Green, and Blue channels as 6 hexadecimal digits (#000000 to #FFFFFF); rgb(r, g, b) uses decimal integers (0–255); and hsl(h, s%, l%) expresses Hue (0–360°), Saturation (0–100%), and Lightness (0–100%).
