About color formats
Colors on screens are commonly expressed in three formats. HEX uses a six-digit hexadecimal code such as #4f46e5. RGB (Red, Green, Blue) describes the same color as three numbers from 0 to 255. HSL (Hue, Saturation, Lightness) expresses color by its angle on the color wheel (0-360°), its purity (0-100%), and its brightness (0-100%). All three describe the same color space and are interconvertible.
