Seeing Red???

[pbadad]

Interesting post. Yesterday saw a show on fishing smallies. Cajon line and Diaichi red hooks were used with shiner bait. The narrator asked the pro guest how does red line disappear and red hooks show up. His statement was that the line is translucent and light flows through causing the disappearance and the red hooks are opaque keeping light to flow through hence red showing up to 70'. Believe what you want. Maybe a subject for Mythbusters!!

Seems to me that that red line would look gray under water. If we see the red above water, it would seem that it isn't very transparent.
