White Light

Anyone help me understand what white light does in a Reef Tank?

Do corals require “white” light?

I note that LFS are running all blue ( for obvious reasons) all day, but is there any long term effect of giving all the spectrums, with an emphasis on blue, but virtually no white?

I do like the “pop” I am getting but don’t want to take away something that would have a negative effect.
