Change colour Effect 1

Hi, i am currently using the free version but will upgrade to the paid if you can help me. I am using effect 1 and would like to change the colours of the circle to match my theme (blue and orange instead of orange and green). Is this a possibility?

Also, when I load the page it seems to zoom in from a square into the circle shape? Is there a way to stop this from happening?
