Don't know if it's fact or not, I heard( saw chart too) on what colors fish see as sun comes up in morning and progresses through day. This chart says fish see green first thing in morning, and last before sun goes down. Now this does not mean they don't see green midday, just that some of the other colors become more distiguishable during concentrations of light intensities. It also suggested that fish may see green as green first thing, changing to red, then to black as light spectrum changes. I wouild be interested if this chart mentioned, was part of this study aforementioned.Thank you all for any more conrete evidence on this interesting topic.
