Eeeek! Where did my background go?

I've had to choose a new background from The Cutest Blog on the Block because my old one 'disappeared'!!
Anyway, it probably needed a revamp and there were lots of lovely backgrounds to choose from. However, I would like to change the colour of the writing for my posts and I have forgotten how to do this!! I know that you can select a colour each time you write a post but I thought you could customise your settings so that all your posts were a default colour.
If anyone knows how to do this, I would really appreciate your help!!

No cards to show you today but I am busy working behind-the-scenes on DT cards for Little Claire Designs. Cant wait to share them with you!

Have a nice weekend xx
