I'm using 2.10.4 on a Windows 10 machine, trying to do colorizations of old photographs.  Is there a way I can change the color I have set for a layer without either deleting & recreating or erasing & redoing it?  Lets say I've made a layer and colored a shirt blue.  That's the only thing on that layer, is there a way I can easily change it to another color?  I thought I would be able to go into the color itself & change the RGB settings, but I can't see a way.

Hope this is clear!  Thanks in advance!

Depends how you are applying the colour.

If it is solid and the layer is in one of the 'modes' say multiply might look like this : https://i.imgur.com/FQygjU4.jpg

Enable the alpha lock, top of the layers dialogue and fill the layer with the new colour: https://i.imgur.com/0dWmNg5.jpg

Plenty of ways, but it depends which color you want to change to what (same lightness, same saturation, same hue?).

• Color>Map>Rotate color
  
• Desaturate and Color>Map>Gradient map
  
• Sample the color, add saturation, bucket-fill in Color-erase mode, then bBucket-fill with the a saturated version of new color in Behind mode.
