My favorite colour is purple. Although when I was younger it used to be yellow for a long time.
Turns out it's common to lose interest in the colour yellow as you get older. I can't perfectly remember the reasoning behind it, but I think it fits in somewhere with the innocence of a child as yellow is the most bright and cheerful colour. As you grow up you lose that connection.
Yeah, I know a thing or two about colour psychology.
I have always been kind of a hipster for saying my favorite colour was sapphire-blue. Don’t know what basic colour I like the most. It’s a pretty meaningless topic to be honest. Just colours. I like all colours.
