[Home2] – Change the color

Hello to the team,

I just bought the theme and I already love it.
I feel that I will build my website quick.

I have a question though concerning the change of some colors.

It concerns the three Banner HTML of the Home 2.
Both the active one and the hovering of the two others.

Actually the image of the product gets rounded by both a pink and blue color.
I need to change these two colors.

Can you tell me how to do that ?

Thanks ,
