I liked it. The repetition of the "twitch of a finger" idea is really good, for some reason I can't explain. Maybe it's the idea that red is easier than the other colors.

Also, the bit about ceilings being white made me laugh. I like the argument to that, I can't imagine any reason why ceilings have to be white.

No grammar or spelling issues that I noticed.

Dry and subtly dark: my two favorite qualities in writing.

Although you are worrying me a bit. Don't paint your ceiling red, okay??

It's really good, though. The ironic casual tone is great. And I'm not just saying that because you called me sweet :)

This is so great!
I would totally paint my ceiling red.
(If, for nothing else, because it's my favourite colour)
I love how this reads, too. I read it over twice and just wanted to do it aloud.
And so I did. :)
'Twas great. Keep scribing,
