8-bit color

This creates a so called 3-3-2 8-bit color image, arranged like on the following table: This process is sub optimal.

[3] Because of the low amount of memory and resultant higher speeds of 8-bit color images, 8-bit color was a common ground among computer graphics development until more memory and higher CPU speeds became readily available to consumers.

Due to this legacy, some image types such as GIF and TIFF use an 8-bit color palette system to store data.

Even though it is now outdated for most consumer applications, 8-bit color encoding can still be useful in imaging systems with limited data bandwidth or memory capacity.

In practice, in order to avoid this problem, most images do not use the full range of 256 colors.
