Can you guess what mine is...? I find this to be so endearing. I love seeing an adult out in the world proudly showing off their favorite color. It also helps with decision paralysis because you always know what color to go for.
Everyone talks about their favorite color aggressively as a child but adults seldom do! It's also very fun because then your friends will get u stuff in that color and life will slowly shift towards the monochromatic 🧡
I used to think I was above it all but it’s actually very useful to have a go-to. also you can then have a secret favourite colour all to yourself (and a trusted few). and when you pick another colour for something it endows Way more significance
