I have one plant that has bright red coloration in 1 trap, and another trap is totally bright green. Then a few have small amounts of red in it.
Is there a reason or significance for that?

I think its true for some orchids, but I'm not sure for venus flytrap.It's true that the red dye, anthocyanin, reflects a significant portion of one of the major frequency bands that plants use, and that a red plant can accommodate intense light much better without burning because of that fact, and that red plants often need more light than green plants as a result, in order to grow at about the same rate as their green-leafed friends. The red inside the traps (not all over the leaves) might have been developed by evolutionary processes to attract insects, however, even though I believe it is caused by the development of the same organic dye (anthocyanin).

Indoors my plants the most colorful they have ever been but since taking them outside in even more intense brighter lighting they all went green.Right, that's to be expected depending on the color temperature of the lights you're using. Outdoor light this time of the year primarily promotes growth, not coloring, so flytraps will be mostly green as they pump out new, healthy growth. Later in the summer and fall, they will start to add color to that growth.

Other traps on another typical vft are lime green (no red whatsoever) and grow to various sizes and vertically straight up into the air. What could explain these stark differences considering same pot, same typical Dionaea muscipula and same location and water?To put it in human terms: Why are some people tall and others are short? Why are some people skinny and others are as wide as they are tall? Why do some people have dark skin and others have pale skin? It's genetics, environment, or combination of the two. Venus flytraps are no different.
