You guys are looking at one or two specific varieties when comparing them to "irl hydrangeas" but they aren't just purple and blue as shown in the picture upthread, lol. As a gardener I need y'all to know that, irl, hydrangeas do come in pink, purple, and blue (as well as white and I've seen some pretty deep reddish ones as well - there are even some that stay eternally greenish). A fair amount of cultivars are represented here if you want to look. 
But yes, it seems like the "pink" variety ingame was a mistranslation bc those are definitely purple. Or the person handling it was colorblind maybe? haha
