djstein, I have to wonder about the idea of a blue color being bad. I don't know for sure but I recall the only two colors that are poor are white and yellow. Since deer and elk only see in black and white you can test the notion by taking a picture with an inexpensive roll of black and white film. You can't really see the difference between white and yellow as I have made this test.
Blue on the otherhand I don't know, but if dogfish hasn't had a problem why should you? Make the test. It may be the blue gloves are just fine.
