Does Color Matter for Fishing Lights?

Does Color Matter?

Which Color Should I Use?

While fisherman have been using White Light for many years, more and more
fisherman have discovered that Green light seems to be attracting more fish.
Does that mean you should throw away your White Lights and fish only with Green
lights? Of course not. But, if the fish aren't gathering with your old White light,
you may want to think about changing to a Green Light, much like you would
change colors of lures if the fishing was slow.

Light Visibility at Depth and Distance

White Light is made up of all colors in the spectrum. When white light passes
through pure water the various wavelengths are absorbed at different rates. The
long wavelengths (reds) are readily absorbed by the water molecules while the
shorter ones (violets) are absorbed at a slower rate and penetrate further into the
water.

The longer wavelengths (reds and oranges) are absorbed nearest the surface, so
at depth these colors are no longer visible. The deeper you go or further away
from the light source you get, the other wavelengths are also slowly absorbed,
Yellow wavelengths start to disappear, then Green. Blue, Indigo and Violet
penetrate the deepest and are visible the longest underwater. For more
information on this process see Fishing Light Attractor.

The below Figure shows the depths to which various wave lengths of light
penetrate crystal clear ocean waters at noon on a calm summers day. As you can
see other than Violet, Blue Light and Green Light penetrate the deepest while still
maintaining their brightness.
