Understanding RGB and LAB Color Spaces
LAB (CIELAB) is a color space designed to be perceptually uniform, meaning that a change of the same amount in a color value should produce a change of about the same visual importance. RGB, on the other hand, is device-dependent and based on how displays create color.
LAB Color Space Components
- L (Lightness): Ranges from 0 (black) to 100 (white)
- A: Green (-) to red (+) axis, typically -128 to +127
- B: Blue (-) to yellow (+) axis, typically -128 to +127
Pro Tip: LAB color space is particularly useful for image processing because it separates lightness from color information and is designed to approximate human vision.
Common Use Cases
- Professional color management
- Image processing and analysis
- Color difference calculations
- Cross-device color matching
- Scientific color analysis
