LEDs are getting more efficient all the time.  Progress is a double
edged sword.

I think it's chromatic aberration, should be perfectly normal.  It's 
just that blue LEDs, being bright, small and on the dispersive end of
the visible spectrum, show this particularly well. 

I believe yellow-green is usually considered the most readable color,
both because it's less distorted by chromatic aberration and because
the eye is most sensitive in that region.
