Select colors finds the parts of the frame matching the colours you pick, leaves them alone, and changes the saturation of everything else. Out of the box that is the classic colour splash — the whole frame goes monochrome and only the selected colour survives
It works the other way round too: switch Invert Selection on and the selected colour is the only thing that drains
Color Slot
There are ten colour slots, edited one at a time through Color Slot: pick the slot to configure, then decide whether it is enabled and what colour it holds
| Slot | Default | Slot | Default |
|---|---|---|---|
| Color 1 | #ff0000 | Color 6 | #ff00ff |
| Color 2 | #ffff00 | Color 7 | #ffffff |
| Color 3 | #00ff00 | Color 8 | #808080 |
| Color 4 | #00ffff | Color 9 | #000000 |
| Color 5 | #0000ff | Color 10 | #ff8800 |
Only Color 1 is enabled by default; the other nine start off. With all ten off the selection is empty, and the whole frame is treated as unselected
Controls
| Control | Range | Default | Effect |
|---|---|---|---|
| Invert Selection | Switch | Off | Swaps the selected and unselected parts |
| Hue Range | 0 – 0.5 | 0.08 | How wide a band of hues each colour matches |
| Saturation Range | 0 – 1 | 1 | How far saturation may differ and still match |
| Brightness Range | 0 – 1 | 1 | How far brightness may differ and still match |
| Unselected Saturation | −1 – 1 | −1 | What happens to colour outside the selection. −1 is fully grey |
| Blend | 0 – 1 | 1 | How much of the adjusted image mixes with the original |
Matching Range
The three range controls together decide whether a pixel counts as a match
Hue Range is the main one, measured as a fraction of the colour wheel — the default 0.08 is roughly 29°, wide enough to catch the light and shade across a red costume without dragging orange in with it. Start small and open it up until everything that should stay does
Saturation Range and Brightness Range both default to 1, meaning neither filters anything and only hue decides. Lower Brightness Range to tell a bright red from a dark one; lower Saturation Range to keep only the vivid parts and let washed-out shades of the same hue go
Unselected Areas and Blend
Unselected Saturation governs what happens outside the selection. The default −1 drains it completely, which is the standard colour splash; 0 leaves it untouched; positive values make it more vivid, so the selection recedes instead
Blend is the master strength for the whole effect. At 1 it applies fully, and lowering it mixes back toward the original — for a gentler "mostly drained but some colour left" result, easing this down reads more naturally than easing the saturation up
Processing Order
Select colors runs after color shift and before blur, as the last step of the colour block
