Okay, so you've downloaded a brush that some lovely person has made. You've put it in your brushes folder. You've opened up the GIMP all excited and tried your new brush, but alas! Your new GIMP brush only paints in black and white. And you really need it to paint in colour.
This is how you fix it.
(Many thanks to Disdainful-Soul.net for giving me the clue to work it out. Also - thanks to the person who made this brush. I don't want to credit them in case they're embarrassed by the fact that I'm "fixing" their work, but please accept my grateful thanks for making this great brush set in the first place!!)
Step 1: Open the brush file itself. You will find it in your brushes folder. It will almost certainly have a .gbr extension. (Note that .gbr stands for "gimp brush" and is similar to the .abr file extensions of Photoshop brushes). Look at the title. Does it say RGB? This is (apparently) the problem - that your brush has been inadvertantly saved in RGB (RedGreenBlue) mode and they will only paint in colour if they're in Greyscale mode.
When you try and paint with it (as below) it will only paint in shades of grey.
Step 2: So the first thing to do is to change the mode to Greyscale. This is done by Image | Mode | Greyscale. (This is not the only step, however...)
Step 3: Give the brush a white background. Merge the two layers. Then "Flatten the image" as below. (Note: I can't explain why "flattening" is so essential, but through trial and error I found that a simple merge was not sufficient. Unless I flattened the image as a separate step, GIMP wouldn't save my .gbr file.)
Step 4: Finally, save your new brush as a .gbr file. Put it in your GIMP brushes folder. Start using it. Et voila! It paints in colour.
This is how you fix it.
