I will, time is now. There is nothing else can be done. But I am going to wait for you come back. You have to tell me about Messian and colors because I don't know much about it. We can not leave my knowledge and such a pitiful state. Please time is now.

From the wikipedia page about Messiaen......
Colour
Colour lies at the heart of Messiaen's music. Messiaen said that the terms "tonal", "modal" and "serial" (and other such terms) are misleading analytical conveniences,[33] and that for him there were no modal, tonal or serial compositions, only music with colour and music without colour.[34] For Messiaen the composers Claudio Monteverdi, Wolfgang Amadeus Mozart, Chopin, Richard Wagner, Mussorgsky and Stravinsky all wrote strongly coloured music.[35] In addition, Messiaen experienced mild synaesthesia, manifested as the experience of colours when he heard or imagined music (he said that he did not perceive the colours visually). In certain of Messiaen's scores, he notated the colours in the music (notably in Couleurs de la Cité Céleste and Des canyons aux étoiles…) — Messiaen's purpose being to aid the conductor in interpretation rather than to specify which colours the listener should experience.
George Benjamin said, when asked what Messiaen's main influence had been on composers, "I think the sheer […] colour has been so influential, […] rather than being a decorative element, [Messiaen showed that colour] could be a structural, a fundamental element, […] the fundamental material of the music itself."[36]
