Palette
All TIC-80 games use a palette of 16 colors drawn from 24-bit colorspace (16 million possible colors). The TIC-80 default palette for all new cartridges is SWEETIE-16. The game's starting palette can be modified using the Sprite Editor in advanced mode.
You can alter the palette at runtime using the poke command and poking into the PALETTE area of VRAM. You can replace the whole palette this way, or just a single color.
For more temporary swaps (within a palette) PALETTE MAP VRAM is what you need. Let's say we have a sprite that's largely blue but now we'd like a variant that's red (replacing all the blue pixels with red). We don't need a second sprite for this - we can just update the palette map.
PALETTE_MAP = 0x3FF0
blue = 9
red = 2
poke4(PALETTE_MAP * 2 + blue, red) -- swap the colors
-- draw the sprite
poke4(PALETTE_MAP * 2 + blue, blue) -- swap them backSee also PALETTE MAP.
By combining poke and SCN creatively you can potentially display up to 2,176 colors on screen simultaneously (16 colors x 136 scanlines). As always, each scanline is still restricted to 16 colors.
Example
Colors used in the code editor can be configured using the console config command.

Some very old cartridges may still use this palette for backwards compatibility.
