I understand being frustrated about the color. Coincidently, I got my Sunny Pastels several years ago, based on the label that said "white, cream, lemon, orange and red flowers" which sounded really fun. There is no indication that this was a mix of different colored plants — it was a gallon pot. It turned out to be dark pink, fading to white. I specifically don't care for pink.
I don't know why your lower leaves are like that, but overall those plants look really healthy. How many did you plant? Fyi, I've moved and divided mine three times in four or five years. Wait till it dies back; it transplants well.
