What colour is caffeine in its pure form?

I take my coffee white.

I am a Boomer. The generation before as well as the generation after us both had serious caffeine addiction.

About 40 years ago we learned at chemistry class that there is theine - alkaloid in the tea leaves and caffeine - alkaloid in the coffee beans. Now IUPAC says there are the same. The science evolves.
