Pixel pen: This one looks almost identical to the marker except that unlike the marker, it colors the entirety of every pixel it reaches.

It's similar to the spray can tool, except that the edges aren't as soft. It's really easy to darken the color of the watercolor brush by simply brushing over the same area more than once.

Watercolor: Use this brush if you need an effect where the color should be faint over some areas, but darker over others.

It has a 'thicker' and more pixelated effect that hides the background image much more than the marker.

Oil brush: The oil brush gives a true brush look.

Its effect is much like the marker's except that the thickness of the strokes change as you speed up and slow down the pen's movement.

Calligraphy pen: This tool works like you'd expect a calligraphy pen to work.

Neighboring pixels that are just out of reach are lightly colored. It's similar to the pixel pen tool, except that it will bleed parts of the color into nearby pixels for a softer approach.

Marker: The marker has a uniform stroke everywhere it's used and has a clean, full look to it.
