(Some graphic programs like Paint Shop Pro allow you to include this system palette in the graphics.) Under Windows, the first 10 and last 10 colours of the palette should be set to fixed values. The colour of each pixel is not directly stored in memory, but as the appropriate number from a list of 256 numbered colours, known as the palette. This means a 320x200 pixel sprite will need 64Kb of memory. A rather old-fashioned graphic mode, also called palettized mode, the colour of each pixel is stored in one byte.
