Probably the PH of the soil in the new Pot you planted them is higher sometimes that affects the colors of the flowers even after blooming I had some that were Pink and my husband dumped coffee close to them and later they turned red wine color ... they survived no worries but they changed color they will go back to the original color if they get non acid soil
