L
L*a*b model
The color model is based on the model proposed by the Commission Internationale d'Eclairage (CIE) in 1931 as an international standard for color measurement. In 1976, this model was refined and named CIE L*a*b. L*a*b color is designed to be device-independent and perceptually uniform. L*a*b color consists of a luminance or lightness component (L*) and two chromatic components: the a* component (from green to red) and the b* component (from blue to yellow).
For more information, see the CIELAB section of the "Color Models" technical guide.
legacy files
Files created in an earlier version of an application that may not include support, or may include less support for some features (e.g., CMS) of the newer version of the application.
lightness
The property of a color that distinguishes white from gray or black.
lossless
Refers to a data compression method that retains all data from the uncompressed file. LZW is a commonly used lossless compression method and is commonly used for TIFF and GIF format files.
lossy
Refers to a data compression method where data is lost through compression. JPEG is a commonly used lossy compression method for images.
luminance
The brightness of a surface determined by the amount of light it emits or reflects.
