It makes it look like REAL LIGHTING, yo! Solid outlines make items look cartoony and weird. And, as my Super Mega Foxy Awesome Hot Tutorial shows, everything looks better in color. Color's how you can test to see if it looks alright or not. I usually check a few different dark and light colors and make touch-ups from there.
You could read and understand everything I wrote, right? XD I've been told that my handwriting is hard to read sometimes so I worry.
