Hi I just tried some brushes from Adobe Brush.
I think Adobe Brush is an amazing product ... it allows countless possibilities.
I used some brush samples with Photoshop Sketch, I'm just wondering is it possible to
color my brush in Adobe Sketch or i have to capture color?
It seams logical to be able to manipulate brush color.
you should be able to change color in sketch, but before you get there, inside Adobe Brush, in the presets options you have to select "color" menu and RGB in it. So Sketch will know that the brush is not a B&W one. Check my pic
If it does not work in sketch, it might depend on the fact that you did not choose this option in Adobe Brush. Give it a try
