Most Windows graphics drivers support a palette of 256K colors ormore, of which only a few can be mapped into the 236 palette indexes at a time. To access and useall colors on the system, bypass the palette and use direct RGB color functions such as such asSETCOLORRGB and SETPIXELSRGB.Any RGB colors can be mapped into the 236 palette indexes. Thus, you could specify a palettewith 236 shades of red. For further details on using different color procedures see "Adding Color"in your user’s guide.In each RGB color value, each of the three colors, red, green and blue, is represented by aneight-bit value (2 hex digits). In the values you specify with REMAPALLPALETTERGB orREMAPPALETTERGB, red is the rightmost byte, followed by green and blue. The RGB value’sinternal structure is as follows:BitRGB31 (MSB) 24 23 16 15 8 7 0O O O O O O O O B B B B B B B B G G G G G G G G R R R R R R R RLarger numbers correspond to stronger color intensity with binary 11111111 (hex FF) themaximum for each of the three components. For example, Z'008080' yields full-intensity red,Z'00FF00' full-intensity green, Z'FF0000' full-intensity blue, and Z'FFFFFF' full-intensity for allthree, resulting in bright white.CompatibilitySTANDARD GRAPHICS QUICKWIN GRAPHICS LIB2-373
