I am curious about properties and research regarding light and photons. Specificially where photons are generated from in the molecular structure of things that emit light. How different color light travels at different speed (or is it just different wave lenghts), are there different speeds of light, etc. Any recommended reading material?

To start off, get a copy of Feynman's QED: The Strange Theory of Light and Matter. Feynman being one of the creators of the modern theory of light and matter (Quantum Electro-Dyanmics, or QED), you can't get a better source, at least at the popular level. But he was also one of the best expositors of science in general (when you have the time, watch his lectures entitled The Character of the Physical Law available at YouTube).
