Question

Observed under magenta colored lights, you see a crayon that appears red. What colors could the crayon be when observed under ordinary white lights?

Choose all that apply.

blue white magenta red cyan black green yellow

I initially thought it would be magenta, red, and yellow, but I think it's only yellow. I'm not 100% positive. I think it's because the blue got absorbed?

I think it's yellow, because, Magenta reflects red and blue colors, absorbs green. With magenta light, the crayon appeared red, not blue.

We know that white light is a reflection of red, blue, and green combined. If the crayon is yellow, it would reflect red and green colors. We already know based on the magenta light that this crayon reflects red for sure. It can't be magenta, because it appeared red only. We know the crayon can't be blue, because the magenta light would have originally made it blue. Thus, it also can't be white, since it needs to reflect all red, blue, and green. Since it's not reflecting blue light, it can't be cyan either. There's light being reflected so it's not possible to be black. And then, I think it can't be green because green absorbs blue and red. Red is being reflected, not absorbed.
