Is It Okay to Eat Cauliflower That Is Beginning to Turn Purple?

Yes, it should be ok. This was either caused by the weather (some cauliflowers grow slightly purple under cooler or unusually hot conditions) or you could have bought a purple cauliflower (if you did not mean too, it was probably mislabled). Either way, it will not harm you. They are just as edible.
