This brush was originally made to vary opacity rather than size. Please adjust any settings to your liking so it may better fit your needs.
In its default state, this brush uses pressure to vary the opacity only. Please adjust any settings to your liking. If you would like to use pressure to vary the size, please check the box and adjust according to your own likes.
This brush works in colour.
