For HG Poetics:

"It is my opinion as well as that of others that the word grey spelled with an e is 'greyer' than the same word spelled with an a: gray.

Can the poet be correct in assigning the color white to this letter [E]? Admitting, therefore, more light to the word so that it becomes itself lighter, creamier, if you will, on the other side of darkness. The blackness of a. Gray holds to itself more blackness than does grey ."
