Color Palette Memory
Updated: April 20, 2023 at 19:42 CESTColor palette memory holds user defined palettes. They can be applied to characters and objects used to create graphics layers.
$9C00 - $9CFF (Write Only)
💡 CRAM has its mirror located at $8C00 where it’s freely modified. Just like with OAM, update is recommended during VBLANK to prevent any glitches.
Color palette memory is organized into 16 slots.
Each palette occupies one slot. It has 8 colors and each color entry takes 2 bytes, being represented by 12-bit BGR value. Unused bits are not set.
| Address | Description |
|---|---|
| $9C00 | palette $00 |
| $9C10 | palette $01 |
| . . . | . . . . . . |
| $9CF0 | palette $0F |
Color 0 of each palette is displayed as transparent for BG_1 and OBJ - they effectively use one color less than BG_0.
Palettes are independent from graphics data which means any object or character can be assigned any palette and have it modified any time.
