Colour theory with Mouses at Greenbelt

 Mouses were fantastic on the Rebel Rouser stage at Greenbelt. Here they are in white light. The drummer has a red shirt on. Colour theory says that white is made of red, green and blue mixed. The red reflects from the shirt into our eyes but the green and blue are absorbed.

Here they are in blue light. This time there is no red to reflect. The blue is absorbed so the shirt looks black.

In red light, the red reflects so the shirt looks red again. Nothing is absorbed by the shirt but we can't tell. Any white surface would normally reflect all of red, green and blue to appear white. However, here only red reflects and so any white surface also appears red.
