Which colias and why...I need to get this ID down...

Orange Sulphur
Another great photo! This is definitely a female Orange Sulphur. Looks like it is nectaring on clover. I have taken hundreds of pictures of this butterfly. They are so much brighter in color than what the camera depicts but we can only capture what the camera will allow. If the wings were open you would see a bright orange spot on the opposite side of the white spot on hind wing. You can also faintly see from this outside shot, the dark marginal bands of black with light yellow splotches breaking up the black outer edges which would be seen if the wings were open. GReat photo! You have a good eye for composition.

Moved from Colias.

Orange Sulphur
I'd say this is an Orange Sulphur. And the way it was told to me to be able to identify these over Clouded Sulphurs is that there will be a little hint of orange on the forewing. In yours, it would be the area beneath the black and white spot, the wing area that's not quite showing much. If there is any orange showing, then that's the identifying characteristic. Compare:

This is another characteristic of Clouded Sulphurs. They have a kind of "cloudy" look all over, not just on the lower wing. Compare:
