If you just want to use each color one at a time, say as an indicator, no problem. But if you want to provide a nice blended color like yellow, they aren't very good. If you use them as an indicator, where you are looking at the LED, you see the three colors clearly and this is even worse off axis. For example if you mix red and green, rather than seeing yellow, from some angles you see mostly green, and from others mostly red. This is true even if you add a lot of diffusion. If you use them as an illuminator, where the LED shines on something else, there are three very distinct color circles rather than a blended color. START SOMETHING.
