Using Independent Bitmap Colour Swatches
When working in the Colour view, by default the current colour is active for both vector and bitmap layers. You can however, use different reference colours for each layer.
When using bitmap colours, there is no longer a link between the painted zones and selected colour. You can edit the colour as much as you want, but your drawing will not be affected. You can still select colours from your vector colour palette to use the same tint, but you will not create links between your drawing and the swatches.
- From the Colour view menu, select Colours > Independent Bitmap Colour.
Whichever colour you choose as the reference color is retained for that layer type.
