The pitch of a sound mostly controls the size for me, so the same sound on different note is very similar. Amplitude makes almost no difference. The texture makes them very unique though. Sub basses, like a deep sine is usually dark yellow for me, or sometimes very dark grey, and they are soft and very large, like an infinite floor. Percussive elements tend to be round. Kickdrums usually look big, round, dark, with a hard and shiny edge if it is a rocky kickdrum with punch, and they look like a sphere cut in half if they are weak. Here are a couple of more examples - Trancy leads are the only sounds which I percieve turquoise - Electro synths tend to be very bright yellow or orange - Drum and bass basses are mudded grimey brown, grey, etc - Flutes, sax and wind instruments are light yellow too, with a really interesting shape - Guitar and similar pluck instruments also amaze me, they are very distinctive - Violins are red, and very shiny, like fire.
