It's French for "Colour."
I thought I'd do everyone a favour and bring colour to their lives. I mean, life would be boring without colour right? But if you're wondering about the origin, most people would probably think it's new and recent considering I change my name a lot, but this name is actually one of my oldest internet aliases.
Back in 2010 (I think it was, I can't even remember), I needed a username for this online game called Megoland. My friends and I used to play it... in fact I think everyone in my grade played it around then. lol. Anyway, back then I considered myself pretty artistic, I'd win all art contests in my school and everyone from my friends, family to teachers said I was exceptionally good at art. So I was thinking of an artistic-sounding name, and the most prominent word that came to my mind was "Colour."
And that's how I got the name Colour, although I only translated it into French recently because I'm obsessed with anything French. ;p
