Mask editor : adds five basic colors <red, green, blue, white, and black> to make color selection more convenient.

### Feature Idea

Now, we have only red color,

I often use the Brush tool to Draw **pure white or pure green** on the image，

Every time I open the editor to modify the mask, I need to reset the color to green/white.....

So, I think adding a few more preset colors will greatly improve operational efficiency. Like this:

**Click once to switch color.**
