Graphics data representing color values of pixels are compressed into a data structure. Each pixel has a color value that results from the combination of a luma component and chroma components. The number of bits representing the luma and chroma components of a pixel are reduced to less than eight bits, and the luma components of at least four pixels and at least two chroma components are combined into a data structure r bits in length. The number of bits of the data structure is derived from r=2<s>, where s is an integer greater than or equal to five.
