This is not a romance. I don't want the colors to be washed out. I don't want it looking schmaltz-y.
No blurry, pale, run-together, looks-like-it's-been sun-bleached look. So no yellow washes.
Woman needs to be wearing professional clothes, and if man is there, so does he.
I like the fonts in the example I shared below, but title should obscure the woman. I also gave you an image of an anemone (but I'd like it with a stem.)
No yellow wash, more NY fashion on the woman, vibrant touches of color (flower not just a sticker on the binding, BLUE water and sky, maybe a touch of orange or yellow, even in the typography, and maybe the UN building (where the character works) instead of the smoldering WTC. It's 1981, for goodness sake! This is a love story not a tragedy.
The image my publisher sent me is below, and the elements are ok, but the colors are not. Plus see my comments above about things to avoid and things I want. Complementary color wheel of blue or turquoise and orange or yellow.
I do like the fonts, but they're illegible.
