If there was much difference at all you would be able to see it. If you
want to know how much light is lost traveling through anything just hold it
up in front of a white wall. Substances with poor transmission qualities
make the wall look darker or will make it appear to be colored or both. The
human eye doesn't do a very good job of discerning wavelengths of light but
it does an outstanding job of measuring light intensity.
