Remove & replace palette colours.

Click a chip to make it the active colour. The first nine chips map to number keys 1–9.

Hover a chip → click × to remove that colour. Every face painted with it reverts to unpainted. Undo-able.

Right-click a painted face → Replace this colour → current swaps that colour for the active palette colour everywhere on the model, in one undo step.

• Switching the active colour mid-paint — click a chip or press its number key (1–9).
• Pruning a palette down to just what you'll print with.
• Swapping a colour scheme: paint with placeholder colours first, then right-click a painted face → Replace this colour → current to map each to a real filament at the end.

1. Activate: click a chip, or press its number key. It becomes the colour you paint with.
2. Remove: hover a chip → click ×. Every face of that colour reverts to unpainted.
3. Bulk replace: make the new colour active, then right-click a face painted in the old colour → Replace this colour → current. One undo step.

• Removed by accident? The faces are unpainted, not gone — Ctrl+Z to undo.
• Replace affects every face of that colour. If you only wanted one face, use Pick + repaint.
• Adding colours lives elsewhere. See Add from library + custom and Theme palettes.
