You'd have to give the specific examples, but without more information, here's my guess:
You either have the same color chosen in preferences, OR you both have colors chosen that are not in the game you're playing, but are considered close to the same color that is in the game.
THEN, when the game starts, if there are multiple premium players, I believe it is randomly chosen as to who gets their first chose color, so sometimes you are getting chosen first, but sometimes it's your friend, and this is causing the color swap.
To avoid it, you would each need to make sure you have preferred colors that are in the game you're playing and are not the same as each other's.

This happens in many games. I will start posting them as they happen, but I can name Fairy Trails and Donuts right off. In some cases both are premium members with preferences set. In one case, on premium member with preferences set, one not premium who can't set preferences. This back and forth color thing with a rematch *!
