I have phlox sublata and true enough it tends to be mauve, but I also have some candystripe. Arabis is a great ground cover and mine is blooming like crazy now. it spreads really well in the summer, in fact I have to take the scissors out to give them a trim to contain them. I must admit that parts of it don't look well in spring. Just dead and yukky, but it takes off and more than makes up for that. But all I have is white. I just googled and saw many with color but they look more like aubrietia than what I have
