Data Structures
struct	PaletteFade
	A colour buffer for all 512 palette colours: the source palette, the shown and target colour channels, their steps, and two pages of packed colours. More...
struct	BattleEffectBuffers
	The colour buffer (heap block 32) that fades the BG and OBJ palettes: the source palette, the shown and target colour channels, their per-frame steps, and two pages of packed RGB555 colours queued each frame. More...

Enumeration Type Documentation

PaletteTransform

enum PaletteTransform

A colour buffer's build mode: below 0x8000 one RGB555 colour for all.

Enumerator
PALETTE_TRANSFORM_FROM_SOURCE	The backdrop colour (palette RAM's first colour) for all.
PALETTE_TRANSFORM_PLAIN	each colour unchanged
PALETTE_TRANSFORM_GREY	grey of brightness (2R + 4G + B) / 7
PALETTE_TRANSFORM_SEPIA
PALETTE_TRANSFORM_WARM
PALETTE_TRANSFORM_MUTED
PALETTE_TRANSFORM_PALE
PALETTE_TRANSFORM_RED
PALETTE_TRANSFORM_WARM2	half R + 6, two thirds G + 4, B - 6
PALETTE_TRANSFORM_FLAGS	From here the TINT, BLEND and SPLIT bits are tested, TINT and BLEND carrying an RGB555 colour in the low 15 bits; any other value is the address of a ready buffer to copy.
PALETTE_TRANSFORM_TINT	The brightness (2R + 4G + B) times the colour carried.
PALETTE_TRANSFORM_BLEND	The brightness R + G + B shared out in the proportions of the colour carried.
PALETTE_TRANSFORM_SPLIT	each colour unchanged
