  - - - subtractive color
        
        created by combining colored media such as paint or ink and the colored media absorb/subtract some parts of color spectrum of light and reflect the others back to the eyes
      - monitor-specific color

    - - Palletes are mathematical tables that define the color of pixel's displayed on the screen
      - are called color lookup tables/CLUTs on Macintosh
      - most common palettes are
        
        24 bit deep (12,772,216 colors)
        
        16 bit (65,536 colors)
        
        8 bit (256 colors)
        
        4 bit (16 colors)
        
        1 bit(black and white)
      - Dithering
        
        process whereby the color value of each pixel is changed to closest matching color value in the target palette
        
        done by using mathematical algorithm
