I can look at a colour I like and get a lovely physical feeling.
I've always had a thing about colours. I love rainbows. I am loathed to choose a fave colour but if I had to royal purple is just special, but I love pink, not the pastel type, more the psychedelic type. Turquoisy colours I love. Cherry Red, egg yolk golden yellow, emerald green, royal blue. I used to hold transparent sweet wrappers up to the window and stare at them, same with food colouring in glass bottles.
Some colours disturb me though, mustard, bilious colours, tomato red. Oh to end on a postiivve note, I love deep turquoise. We used to have this cleaning fluid called clean o pine which was a dark turquoise and I used to pour some in the sink and dilute it to watch the colours.
Although the kind of pink I like, bright pink, is not on the rainbow, it seems to have a spiritual feel for me, or maybe thats just from past psychdedelic visual experiences as I used to see a lot of patterns with that colour in.
Magenta is another colour I love, i could go on but I would probably fill up a ton of pages.
