I take it back. While the above sentence is true, I thought about it for a
bit, and realized that if you develop with an assumed_gamma other than 1,
the fact that you're specifying colors weirdly makes things react
incorrectly in certain parts of raytracing.

For instance, a full white should appear twice as bright as a mid gray when
they're multiplied by 0.5 (for instance, when they're reflected off a
surface with a reflection value of 0.5). But if you're developing with an
assumed_gamma other than 1, which means your mid gray isn't rgb(.5,.5,.5),
the multiplication by .5 brings the white and gray down to other areas of
the 0-1 range, where they may no longer appear one twice as bright as the
other.

I'm glad I figured that out. Thanks for pointing this little fact out to me.

How frustrating! Now I realize that I should actually use gamma correction!
