Palette swapping

As explained in The Creative Programmer

Palette swapping is a graphics technique that changes the color mapping applied to an existing image or sprite to produce visual variants.

Palette swapping changes an existing game's color treatment to create visual variation without storing another full sprite. It is a small trick with a big lesson: constraints can encourage inventive design. section 4.4.3

On Game Boy hardware, palette swapping helps:

  • Create variations of enemies while conserving scarce VRAM. section 4.4.3
  • Show that Wario has been hit without cluttering memory with another sprite. section 4.4.3

How The Creative Programmer covers it

How deep it goes
Connects the technique to Game Boy memory constraints and gives its purpose, but does not detail implementation steps.
Examples
Uses Wario Land enemies and Wario-hit states as examples of palette-swapping variants.
What you can do after
Evaluate/understand palette swapping as a constraint-driven alternative to storing additional sprite assets.
How it connects
Ties palette swapping to sprites, VRAM, Game Boy hardware limitations, and retro game development.
