an enigma wrapped in a contradiction

Why is it color more so than colour?
I say lets bring back colour. BTW, my mac says colour is incorrect.

It seems to have been a slippery slope, from colour, to color, ...to rsvp, ...to asap, ...to FYI, to btw, to..? what? no talking?
just silent drones texting constantly and when we aren't texting we are getting re constructive surgery on our thumbs. sounds rough... so I say, bring colour back. spell things out. CAPITALIZE your I's... which i never do..
This coming from the one person who likes her broken-technological-driven English, and doesn't seem to care about correct sentence structure.
