I love to use green with pink, and vice versa. It's my favorite color combination, the most complimentary mix I know of. Pink doesn't go with every color, though. For example, I think pink and dark blue or navy blue are usually wretched when placed beside each other. I've ruined many pink florals by trying to add a dark indigo background. I hope I won't make that mistake again. While pink and green are my favorite compliments, pink is also the best color to "grey down" a sharp green.
