Watercolors can add really cool textures to abstract paintings, but they come with some challenges:

• Inconsistency: Getting the effects you want can be tricky. Sometimes it works, and sometimes it doesn’t because watercolors can be unpredictable.

• Control: It's hard to keep things under control. Water can mix with the colors in ways that you didn’t expect.

• Layering: Layering colors is not easy. With watercolors, it’s tough to put down a new layer without messing up the ones underneath.

Here are some tips for artists to handle these issues:

1. Get to know how long it takes for watercolors to dry.
2. Practice on different surfaces to see how they change the textures.
3. Try mixing watercolors with other materials for better stability.
