The Rhombus Array

If you have a digital camera may well at some point have come across a white balance button. Anyone who has ever been camping in a green tent will know first hand that what appears to be white to one eye, might not do to another.

Not all whites are white. They very in temperature from red to blue.

Temperature?

Red and Blue?

Why is Red always Hot, and Blue always Cold? Blue things are not always cold (gas flames), and nor are red things always hot (a tomato straight from the fridge). Funny, innit?
