What is RGB?
RGB (Red, Green, Blue) is a color model used in digital displays, combining different intensities of red, green, and blue to create a wide range of colors. Each color is represented by values between 0 and 255. At full intensity (255, 255, 255), the result is white; at zero intensity (0, 0, 0), it’s black.
Variations of RGB:
- RGB 0-1: Uses decimals (0 to 1) instead of 0-255.
- RGB565: A 16-bit format with 5 bits for red, 6 for green, and 5 for blue.
What is RGBA?
RGBA adds an Alpha channel to RGB, controlling opacity. The alpha value ranges from 0 (transparent) to 1 (opaque), allowing for semi-transparent effects in designs.
What is an RGB Color Picker?
An RGB Color Picker allows users to mix red, green, and blue to create specific colors and get their RGB code. Some pickers include Hue, Saturation, and Brightness (HSB) modes for easier adjustments.
What is CMYK?
CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model used in printing, opposite to RGB’s additive model for screens. RGB adds light to create colors, while CMYK subtracts light.
