Image color changer: replace one color with another

Switch to “Every pixel of a colour”, tap the colour in the picture and pick the new one. The Colour range slider sets how close a hue must be to change; greys, whites and blacks are left alone.

Tap the object: the tool selects the connected area of similar colour, kept inside or outside the photo's main subject outline, and recolours it with the colour you pick. Tap more parts (wheels, a sleeve) to add them; Clear starts again. If too little or too much is selected, move the Tolerance slider.

Only the hue (and the saturation, relative to the original) changes. Each pixel keeps its own lightness, so folds, shadows, reflections and texture stay exactly where they were.

Very dark or almost white objects have little colour to shift: they take the new hue but stay dark or light. Objects with many colours (prints, patterns) may need two taps in the colour mode. Hair and fine edges follow the colour of the pixels, not a cut-out.

A background-removal model (the same one as Remove background) finds the main subject's outline once per photo, on your device; it is downloaded on first use and then cached. The colour selection and the recolouring are plain image processing.
