2 Choose your Brush modes

In Normal mode, colour slowly fades from the brush and blends on the canvas, and this continues until a new stroke is painted. A brush in Permanent mode has an infinite Loading setting and the colour doesn’t fade. Dirty mode blends colours together and when you paint a new stroke, you produce a blend of colours. A Clean brush isn’t loaded with any colour and is always recoloured by the colour it passes across on the canvas.
