This is interesting because the objects on the bottom of the sea developed their colors in relation to the filtration of light. Changing the light to see what they would look like in surface light is an odd choice.
We had a similar thing in a city we lived in they said they could fix the potholes on our street in ten years. Turned out everyone was being told the same thing and eventualy the city had to fix everyone's potholes. (we did end up raising taxes for it though so it wasn't entirely a win)
