Limited color palettes

Retro pixel art looks like retro hardware because those machines could not spend many unique colors on a sprite or a tile. A 16-color set already feels like a late-80s console tile; 32 colors still read as graphic. Hundreds of colors start to look like a compressed photograph on a coarse grid.

Pixelizer’s Max Colors control is a hard budget from 2 to 256. It is not a suggestion. Every quantizer — Median Cut, K-Means, NeuQuant, Octree — has to land inside that cap. The sunflowers above use 16 colors on a 44×44 grid with K-Means: yellows collapse into a few flats instead of a continuous bloom.

Sixteen is a useful default when you want posterization without going two-tone. Thirty-two keeps extra ramps for skin, sky, or metal while still forcing decisions. Drop toward 8 or 4 when you want a stamp or a 1-bit-adjacent icon. Climb toward 64+ only when the grid is large enough that extra swatches do not turn back into noise.

After convert, recolor the extracted palette. Changing a swatch updates every cell that used it — faster than painting the same correction by hand. That is the studio step one-shot converters skip.

Error diffusion and ordered (Bayer) dither can fake extra shades inside a tiny budget. Keep intensity low, or off, when you need clean sprite flats — see game sprites. Turn it on when a sky or a gradient bands too hard.

Engine choice still matters at the same color count. Read Median Cut vs K-Means vs NeuQuant vs Octree before you blame the budget.
