Choosing
what type of outlines to use is basically when you decide on the
style you are aiming for. As I said before, black outlines usually
give your scenes a cartoonish feel (combined with bright happy
colours ^_^). The other type of outline needs a bit of explaining.
Basically what you do is grab the colour of the object you're
outlining and darken it until its in the middle of the original
colour but not too darkened. About 2 or 3 times as dark as the
original colour was. See example below.
