A built-in add-on in Effect › Color Effects and Object › Plug-ins › Color Effects:
- Exposure (stops of linear light, offset and gamma), Desaturate and
Invert Colors as live colour adjustments, evaluated in stack order with
those of Effect › Color Adjustments.
- addon.color.filter applies any colour adjustment to the colours
themselves, through the Edit Colors pass, as one undo step.
- A panel picks an adjustment and its values, then adds it as a live
effect or applies it as a filter.
The add-on lives in its own modules (effects, engine and ui-egui addons
folders) and leaves the existing effects, commands and menus as they
were.
