My guess is that fish avoid nets when there is high visual contrast and that
"color" is secondary in importance. Years ago, Neil Douglas color-coded his
seines, dyeing the 5-, 10- and 20-ft lengths a different color so they could
be quickly grabbed and identified from a distance when rolled up and stored.
He used red, green, and blue with no recognizable effect on capture rates.
The colors were all fairly dark, however, and presented little contrast in
most water colors and clarities.
