| This is a frame taken from the video beside. The blue color is because white light does penetrate to a depth of 8 metres, so only the parts of the picture that are illuminated from the video light show the true colors.. Note in the video how objects appear to change color when illuminated, but, they don't actually do so. In the foreground is a broooding anemone , red with a band of babies at its girth. The pink coral is hydrocoral |
