Torches and the spell Dancing Lights look great with their natural yellow glow.
The Light spell and Darkvision not so much-- especially the Light spell. The Blue/Green color is very overpowering and unnatural -- I understand the desire to seperate them visually, however it would be nice to have an option to make them resemble natural light.

Also the Light spell in particular causes a massive brightness on the character during cutscenes that looks horrid.
