Why is it that you US Americans are so dense in being the main character. Just write USA in the header for a post in an international news channel. Like - you know - every other country in the world. You must agree that this would be the most civil solution or not?

In my understanding you are right for the Blue because it is further away. For red, the situation is similar to green in that most wavelengths excite both red and green. The idea to focus the lasers only on the green cells leaves no red in the impression. Focusing only on the red cell will cause a unique colour accordingly.
