Understanding CSS Color Representations
HEX color codes use hexadecimal notation (base-16) to define red, green, and blue components. RGB uses decimal numbers (0-255) for red, green, and blue. RGBA adds a fourth alpha channel (0.0 to 1.0) controlling transparency.
Converting HEX to RGBA allows developers to set semi-transparent overlays in CSS without affecting child element opacity.
