Brick color

[sl60]

I'd like to experiment with fill in the color of a line drawing of a brick wall, let's say to a red color. Is there a way to do this without having to color in each brick one at a time? How about changing from one color to another, say red to tan?

• Replace the current color with transparency  (Color>Color to alpha, after possibly adding an alpha-channel)
  
• Add a layer below the layer with the bricks
  
• Bucket -fill it with any color you want to try.

Thanks for that but it didn't work!

Care to post (an extract of) the picture and tell why it didn't work?

It would certainly help if the purpose is known. Is it fill in a: Line drawing with perspective / Flat (normal viewpoint) surfaces perhaps for model construction / Modifing an actual photography ?

As previous a transparent pattern and a colour layer under is the way to go.

However a beginner sometimes needs a pointer to a better workflow. I would suggest  the usual, use as many layers as required  but in addition use layer groups to isolate various aspects of an image. Even better is using layer masks, one-thing -at -a time.

Something like this: coloured layer under the brick pattern. Different colours depending on layer visibility. Note the alpha lock to confine the coloured area.
