Introduction and discussion of human vision.
Some people cannot see in all colours - they are colourblind. Colourblindness can be very mild or more severe. At night, none of us can see in colour.
People that are completely blind use their other senses more.

Light attraction by brine shrimp experiment, to find out that brine shrimp move towards green-blue light, most likely to find food.

Experiment with coloured filters to look at undersea drawings.
In the blue of the ocean, animals use colour to camouflage against the dark rocks.
