At this time there are no different brushes in Recolor. There are two different coloring options, the regular coloring and the crayons. With regular color palettes, you can fill the whole area in a picture with a simple click or a swipe. With crayons you can color as if you are using real pencils to color - Crayons let you add to the pictures, for example modifying the designs, adding shading or writing text, and crayons are also the best tool to color imports which don't have clear black lines. When using crayons, you can toggle between softer regular crayons and sharper markers by clicking on the purple dot above the picture. To get a smaller line when drawing with crayons, zoom in close to the picture.
