Color and gray scale The basic attribute for all primitives is color o In a color raster system, the number of colors available depends on the amount of storage per pixel in the frame buffer Two ways to store the color information ● RGB color code o directly stored in the frame buffer E. g: resolution-1024X1024, a full-color(24-bit per pixel)color system 3 megabytes of storage for the frame buffer Color index value(next slide) it references a color lookup tableColor and Gray Scale  The basic attribute for all primitives iscolor.  In a color raster system, the number of colors available depends on the amount of storage per pixel in the frame buffer.  Two ways to store the color information  RGB colorcode  directly stored in the frame buffer  E.g.: resolution - 1024X1024, a full-color (24-bit per pixel) color system 3 megabytes of storage for the frame buffer  Color index value (nextslide)  it references a color lookup table 12
