luka uncolored

for those who dint like the colored luka this is the uncolored. i have no idea what tool is good for coloring because im new to the tablet plus, i tried almost everything that seemed nice but i cant seem to find a tool that gives out a solid color, not like watercolor-ish if anyone wants to help just comment anywhere. im using corel painter essentials 4 so if any of you plan on helping it would be deeply appreciated
