I read a book last year that really got into this same subject. I forget the name but will find out and post the title here. It was very scientific and in most cases boring but I found the chapter on how fish see kinda interesting. A fish's eye changes throughout the day. More specifically, the cones in the eye.
Fish see colors differently at different depths as the above chart shows but they also see colors differently in the morning then they do in the afternoon. It's very complex.
Thanks for the chart, it's a great tool.
