CFLs are horrible for picture taking

Especially when you're taking that picture with your cell phone.

Case in point: Here is a picture of a nice tweedy yarn:

Yarn. Tweedy. Is actually green.

What colour would you say this yarn is? Judging from the picture, a sort of greyish-blue right?

Wrong. This yarn, in reality, is green. Yes. I'm sure. It's really, truly green. A light spring green, like new growth on a willow tree.

CFLs make liars of cellphone cameras.
