About Color Formats

HEX colors like #2563EB are 6-character codes used in CSS and web design. Each pair of characters (25, 63, EB) represents the Red, Green, and Blue values in hexadecimal. RGB uses decimal values 0–255 for each channel and is used in CSS as rgb(37, 99, 235). HSL (Hue, Saturation, Lightness) is more intuitive for humans — hue is 0–360° on the color wheel, saturation and lightness are 0–100%.
