Awww how sweet!! I'm sure its an exciting time, I remember waiting to go pick my little one up. That's great the breeder insists on keeping her til 12 weeks, I wish more breeders would do that!
As for colors, since its Mother's Day and the puppy is a girl, you could use pink colors. Pink/brown, pink/gold, light pink/dark pink...there are so many combinations you could choose, best of luck and congratulations!
