When you spin a torch in the dark, you will see a circle of light, and when you do it properly, you can even write with light. It is a trick that can often be seen on photos, and that Davis wants to investigate in Studies in Color. But a lamp is not only a source of light, it is also a source of different colours, which become visible when you refract the light. Sometimes the light seems to be red, sometimes orange, and then again yellow, and from close by light looks different to from far away. 'Pollution' by other sources of light, such as headlights and neon signs, can also cause interference; Davis explores it all.
