CGRAM

CGRAM (Color Generator^[2] RAM) is where palettes are stored. The SNES uses 15-bit color here. It is a total of 512 bytes. For each of the 256 color entries:

• bits 0 to 4 are the red intensity
• bits 5 to 9 are the green intensity
• bits 10 to 14 are the blue intensity

In all background modes, sprites use the second half of CGRAM.

When using CGRAM, color entries can be one of 32,768 colors from the master palette.
