Prob a load of crap, but then again some species are more sensitive to light then others. Are we talking a actual blue light or acintic blue light? I'd hate to live under a blue light all day, the fish prob would too 
It's not a problem as far as I know, I've done it before and know others who have. My frontosa looked especially cool in blue. That being said, I usually avoid it because the spectrum doesn't help me very much and seems to grow its own specific types of algae in my setups.
I have Blue lights and full spectrum lights together on one of my 120's . I have s. Fryeri,Frontosa'a and Rhodesii in the tanks. The blue lights make the Blues in these fish "pop". I have not seen any adverse impacts.
I had blue T5 lights set up on my 55g at one point for nighttime settings. My fish didn't seem to mind it....
