Do gerberas change colour?
This year I have bought quite a few different coloured gerberas but after the initial flowering 3 of them have flowered again but the colours are now all creamy outer rows of petals with darker inner rows
Without seeing your plants its hard to say what would be happening but sometimes this can happen when there is a distinct weather change. Make sure they are growing in the full sun, feed with a food that has plenty of potassium like Yates Thrive Flower & Fruit Soluble Plant Food and make sure they have very good drainage.
