The _color key in worldspawn has a default value of 0 0 0.  Since people are 
familiar with the _color key in light entities having a default value of 1 1 1 
(which is noted in entities.def), this difference can be confusing, making 
people wonder why ambient lighting isn't working when they didn't specify a 
_color in worldspawn.

It would be nice for the worldspawn entry in entities.def to note that the 
default _color is 0 0 0.
