Firstly, I think everyone (or at least, many people) has the exact same solipsistic colour question pop up at some point in childhood. It's a logical question to ask, and I'm not going to try to persuade you into any conclusion! Secondly, if you're worried about taking psychedelics, don't take them. If you're intrigued, do more research, speak to more people, and see if your worries are diminished by the answers you find. If you feel more comfortable with the prospect of psychedelics after that, then maybe give one a try. It's very important to be comfortable with the idea of taking psychedelics if you're going to get anything out of the experience. It's highly unlikely (but not unprecedented) that you will do permanent harm, but you may have a temporarily unpleasant, or even just neutral, or boring experience. Regarding your question, these feelings are more intense during an LSD trip, but it's the analysis and digestion of these feelings which, in part, can lead to a change in outlook after an LSD trip. I advise, if you choose to try psychedelics, to be in a positive state of mind, be with one or more people who you know, love and trust, and to have at least one person present who doesn't take anything. This person is your spotter. They are there to ensure that you don't come to physical harm, and they can also help to remind you that the psychedelic state is temporary, and you will be fine, in the off chance you aren't having a good time. This person would ideally be somewhat experienced in the psychedelic experience,and also be a known, trusted friend. I know this sounds complicated, and many may disagree with me, but it's my advice for first time psychedelic experimenters.
