Broken TV?
Science brain teasers require understanding of the physical or biological world and the laws that govern it.
Xavier and Rex each own a television. They watched the exact same programme at the exact same time. However what looked like white on Xavier's television looked yellow on Rex's. In this case, what color would cyan, on Xavier's, look like on Rex's, and why?
Answer
Cyan would look like green. This is because pixels are made up of a red light, a green light and a blue light. All three of these colors are required to make white. The blue lights in Rex's television don't work, so the red light mixed with the green light, without the blue light, makes yellow. Similarly, you need blue and green to make cyan. Since there is no blue, what would be cyan looks green.

| Intended answer was obvious enough, but I wonder with regular CRT TV's if it's truly possible for all the blue lights to simultenously die. Digital TV's perhaps, as I suspect it's possible for the "blue" signal carrier to get broken (cf. computer monitors when a pin is broken on the cable). |

| Why all the negative comments? I thought it was interesting, although easy for me... 
If you don't have something good to say, don't say it. You don't ALWAYS have to post a comment, you know!!!
Great job, QuestionMark! |

| I thought this was good. I didn't get it, but I learned something.
If some of you didn't like it, say WHY instead of just stating your dislike. ;) |

| Yes, all the blue can fail at once on a CRT. There is one electron gun for each of the primary colors. If any part of the processing circuitry fails for one of R, G, or B signal paths, that color will drop out of the picture completely. |
