At least, according to this website, which scanned my Instagram account and assembled this color palette.
I bet the year I spent taking only photos in black and white had something to do with this. I’ve also noticed that, when I take pictures with my iPhone, I tend to use the sky as a background, which might account for all the blue.
Addendum: After glancing in my closet today, I realized that that color palette corresponds almost exactly with my wardrobe. Spooky.
