If I gave him a picture of a pink rose surrounded by yellow roses, what would the underlying rose code be?

Gotta send a picture cause I can't really afford a full bouquet of real ones, but anyway. I'm only considering roses at all because he was the one that told me that the yellow rose signifies friendship, and the 10+ web pages I've read tell me that pink means gratitude and happiness. What do all of you fine ladies and gents think? Is a rose gram a good idea at all? (secondary option is a cheesy rap consisting of "pink and yellow pink and yellow pink and yellow pink and yellow")
