I am having the hardest time trying to get colors correct. As you can see my colors are totally different from my color picker and v-ray, yet I am using the same numbers.

I guess it’s because in MAX gamma setting pannel you have “Affect Color Selector” enabled so the values you put in the MAX color selector dialog have a 2.2 gamma applied.
To get the same color than in ColorPic you can try to change VRayColor Gamma Correction settings:
