Color Formats Explained
HEX (Hexadecimal)
HEX is a six-digit code representing RGB values in base-16 format. It's the most common format for web design, used in CSS, HTML, and design software. Example: #FF5733 represents a vibrant orange-red color.
RGB (Red, Green, Blue)
RGB defines colors by mixing red, green, and blue light. Each value ranges from 0 to 255. Used in digital displays, monitors, and web design. Example: rgb(255, 87, 51) creates the same orange-red as the HEX example.
RGBA (Red, Green, Blue, Alpha)
RGBA adds an alpha channel for opacity/transparency. Alpha ranges from 0 (fully transparent) to 1 (fully opaque). Essential for overlays, shadows, and layered designs.
HSL (Hue, Saturation, Lightness)
HSL is a more intuitive color representation. Hue (0-360°) represents the color wheel position, Saturation (0-100%) represents color intensity, and Lightness (0-100%) represents brightness. Preferred by many designers for its natural adjustment.
CMYK (Cyan, Magenta, Yellow, Key/Black)
CMYK is used for print design. Values represent percentages of cyan, magenta, yellow, and black ink. Essential for preparing designs for professional printing.
HSV (Hue, Saturation, Value)
HSV is similar to HSL but uses Value (brightness) instead of Lightness. Common in color picking tools and image editing software.
