I see earlier post you are now using Gimp 2.10
Can you post the brush you are using and screenshot as previous post?
Is it one of the stock Gimp brushes or something else. An example of RGB versus Grayscale is easily demonstrated in Gimp 2.10 where the clipboard brush (from a selection) has a 'mask' version = grayscale. That will take the Foreground colour.
If the brush is not solid black / white then there are 'shades' of the foreground colour, not solid.
