"Like kindergarten 10 o'clock in the morning light"

Working by analogy from Philip Guston's paintings of the 1950s, is it possible to talk about light in the poem?

I remember Berrigan discussing light & colour in 'Talking in Tranquility', the interview with Tom Clark. He's explaining the effect of different times of day upon his - & other's - poems:

"Yeah. I also like to use the famous light at 5.15 a.m.. Like when the sun is sort of up, but it's only a quarter of the way up." (p.22)

However, is he implying more than simply notation? Putting it another way: can a poem have its own light?

Developing the analogy with Guston further*, how do we discern the equivalent of painterly 'touch' in a poem? Certain preferences for placement of verbs or adjectives? Tenses? Syntactical inversions or slippages? When/when not to break a line? A tendency to use long vowel sounds? Soft consonants? ... I'm going to think about this.


(* or, for that matter, Morton Feldman composing as described by Toru Takemitsu: "He was extremely nearsighted and wrote his music as if touching the notes with his eyes. Whenever I hear his music I think of its tactile quality, of his eyes ’hearing’ the sounds.")
