There’s a psychology to colors that is unquestionable. The challenge is in understanding what the different colors mean to people when seen in different venues. On Instagram, blue seems to have the most positive influence on user sentiment.
It’s very easy to fall in love with Instagram, if you’re not already on the bandwagon. You get to express your artistry through beautifully filtered square images and you get to enjoy feedback from other users in the community. Don’t lie, you want the Likes as much as anyone else does.
