Everytime I listen to Goa/Psy I always see colours and fractals. Actually this goes for any music, but with Psy the effect is really intense. For me every track is colourful and while most of them have many colours there's a particular one or two colours that stand out.
Sometimes I associate colours with not just tracks, but groups as well as long the artist has a unique sound.
For example for me MFG were always green. The early tracks were green with hints of yellow, while the darker tracks are dark green. Sometimes I'm influenced by the color of the cover, but most of them times is unrelated.
So I decided to post some tracks and the colours I imagine. It would be cool to post yours.
Like I said I will post only the primary colours.
Astral Projection-People Can Fly
Hallucinogen-LSD
MFG-Intelligent Machine
Talamasca-Talafrica
Chi-A.D.-Biocandy
Astral Projection-Enlightened Evolution
Etnica-Vimana
Actually the green in Etnica tracks is much more 'spacey and liquid', but I couldn't do it properly in photoshop.
Then there are tracks like Pleiadians-Electra were all colours are 'equal' and there are so many that it looks like an explosion.
