Why Yellow Fly Tying Materials May Appear Black To Fish

Postby Karl Klavon » Tue Jul 05, 2016 11:18 am

The following is a link to a book review of Reed Curry's book - The New Scientific Angling - Trout and Ultraviolet Vision - which is interesting enough in its own right to be worth reading but, it is the side X side photos of the same fly tying materials (left side in normal photography and the right side in UV photography) that will really illustrate what I am talking about in the title above.

There is text included to explain what is being shown with the photos but, unfortunately, the print is small enough that it is very difficult for these old eyes to read, so pay particular attention to the second bucktail in from the left (the yellow one), and how black it appears in the UV photo on the right. While the gray bucktail above is also very dull in the UV, but the white bucktail is a vivid pink in the UV photo. Just some food for thought on why the fish may be seeing things very differently from the way these fly tying materials appear to us; here is the link:
