I find this to be a very dangerous and misleading idea, and also a rather common one amongst new drug users. I don't know if leggomyego here is new to the drug world, but I know that this "intensifying" thing is a common misconception. In my experience, drugs do not ENHANCE perception but they DISTORT it. I'm not saying it is a good or a bad thing, I'm just saying that when you're high red is not just redder, and soft is not just softer, but they are simply different. Things are perceived in a different way. This sometimes means that bright will be brighter, but it also means a lot of other things that cannot be described as simple "intensification" or "enhancement" of reality. A much deeper change is happening to perception.
