I have a bunch of custom brushes, and I've saved them as another brush pack. But when I load the default brushes, and then go back to my custom brushes, all the default brushes are there too. I know I can Option- click one brush at a time to delete them from the pack, but if I load a different pack, then come back to this pack, they're all there again. Is there any way to keep the default brushes from showing up when I load my custom brush pack?
Brushes don't have a keep color command, but tool presets do.
No, when you select the tool, all the settings associated with the tool are loaded. If you want another color, you'd have to select it afterward.
But you could select the tool, and create a new tool preset that doesn't include the color.
