This is a great idea

That's lovely, I tell my friend stories of my childhood when she's upset cause it makes her feel warm

I send my friends videos and photos of my cat

*best friend

*Sits back with a bowl of popcorn, waiting for someone to say, "They spelled color wrong."*

I wish I had something like this.

I tell people embarassing stories about me ahah

1) That's adorable.
2) The colour a person is "feeling" at a particular moment often reflects their mental state at that moment, so the friend can quite accurately guess how she's feeling by what color she prefers at that moment. It's not only a super nice thing to do but also very smart.

Wow. Incredibly heartwarming!
