Recolor & Palette Swap

The technique is as old as sprite hardware. Early consoles could not afford a second set of frames for a stronger enemy, so they pointed the same sprite at a different palette and shipped a red one alongside the green one. Players read it instantly: same shape, different colour, expect a harder fight. Team colours in a multiplayer game, seasonal reskins, elite variants, and the classic first act enemy that returns tinted purple are all the same trick.

The economics still hold. A recolor costs seconds and a redraw costs an afternoon, so a recolor is what you reach for when the content needs to double in size and the art budget does not.

The global controls treat the sheet as an image and push hue, saturation, brightness, contrast, and sepia across every frame at once. This is the fast route. Drag the hue slider and the entire character rotates around the colour wheel with the relationships between its colours intact, which is why the result still looks like art rather than a paint spill. A shift of about 180 degrees takes blue to orange, roughly 120 takes it to green, and the preview follows your drag so you can stop where it looks right.

Per colour mapping is the surgical route. Open a frame and its actual palette is listed out, every distinct colour in the image. Click one, choose what replaces it, and only that colour changes. This is what you need when a hue rotation would drag something along that should not move, most often skin tones, metal, or a white highlight that turns a shade of green nobody wanted.

The two combine well. Rotate the hue to get most of the way there, then map the two or three colours the rotation ruined back to something sensible.

Work one variant at a time. Get the swap right on a single frame, judge it, then push it through the rest of the layer in one action so every frame agrees. Export that version, reset the adjustments, and start the next one from the original art rather than from the last variant, which keeps small errors from stacking up across a family of five enemies.

Global adjustments are non destructive and reset with one click, so the original frames survive any amount of experimenting. Per frame mappings commit when you apply them, and the editor history is the way back if one was a mistake. Either way the settings ride along in a saved project, a share link, and a cloud save, so a variant can be reopened later and adjusted rather than rebuilt from memory.

The ten presets cover the recolors that come up most: grayscale for a petrified or disabled state, inverted hue for a straight opposite, vivid and muted for pushing or pulling intensity, warm and cool for time of day variants, negative and sepia for effects, plus high contrast and washed for readability extremes.

Treat them as a first move. Click the one closest to what you want, then adjust from there with the individual sliders, because a preset knows nothing about your palette. Grayscale on a sprite that relied on colour rather than value contrast comes out flat, and the fix is a contrast nudge that no preset can guess.
