Many composers had this. Scriabin had it and it is quite evident in his music. I recall seeing a table he made for all 12 pitches in a book. ---My personal take on some colours. These are for individual pitches only, a mode or chord may give different colours. C - 18% grey (like what photographers use to calibrate cameras)Db - mustardD - greenishEb - navy blueE - BlueF - brownish, redishF# - crystalG - sunnyAb - purple, or deep forest coloursA - orangeBb - brass, or blackB - stainless steel
Actually, for Scriabin, F# was a blue with a metallic sheen... this helps a lot when trying to understand his fourth sonata.
