Chose source and target colours but Replace remains unclickable. 24.08 version.
- Is the image on a layer that has been set to Locked? It can’t alter it until the layer is unlocked
- Is the object not an image but a Shape? You can’t use Colour Replacer for Fills or Lines in Shapes, see tdf#153438 and tdf#123766
Not locked - but you are correct, I was trying to replace in Shapes. It had not occurred to me that this was a bitmap (and bitmap only at that) tool. I agree with the notes in the 2019 issue you linked - it should be for shapes.
My use case was trying to change all shades of some blue I had used on lines and boxes across multiple slides in Impress.
Thanks for the great work and your help.
A common drawing style might have made it a quick single change operation.
Agreed. Novice error.
