1. Do you know why life rafts and vests are orange? It’s because orange and blue are complementary colors; the combination provides high contrast and visibility. This helps people on ships or planes spot the raft or vest.

2. Red and cyan glasses are used to produce 3D images that can be viewed on computer screens.
