Help with custom Gimp brushes

I made some custom brushes in Gimp 2.8.6 and saved them as .gbr files, but when I try to paint with them they do not use the active color, instead they paint with the black color I used to make them.

I have not made custom brushes before, so I don’t know what to do.:spin:

Is this a bug or am I doing something wrong?

Hello. You see if this is the problem you have:

Now I can use my brushes, thank you very much!

just go to edit copy the part you want as brush then edit- paste as new brush. you can use images (real photos and images with alpha channel) also.
I think it is much easier
