The exact question asks

"If red, yellow, and blue colors are mixed, the result is"
A. white
B. black
C. brown
D. purple

(For those with the book, I'm referring to EK Phys 1001 #901).

The answer in the back says it's white. But I thought that if you mixed the additive primary colors (red, green, and blue), then you get white. But if you mix the three subtractive primary colors (red, yellow, blue), then you get black.

Can someone verify that the answer key is in error here?

brown makes the most sense to me.

I remember something along the line of mixing light of different wavelengths is alot different then mixing colors lol so doubtful it would be black or brown

Well, red and blue make purple right? Then you add yellow. I guess it would be brown.

I wouldn't be black, that's for sure. And, it wouldn't be purple.

I would definitely use process of elim.
