Product Variant Options - Broadcast Theme

[HubbaStubba]

Hi there, 

I am placing the finishing touches to my product page and have come unstuck with my 'Product Variant' section.

Specifically the buttons selecting the size of my products is the issue. I would like to the buttons to be very clearly different so that the customers know which size they are selecting. 

At the moment I have the selected product button as the yellow colour. But this is where the problem is... I would like the size button that is NOT being selected to be transparent. At the moment it is almost like it is a shaded background but when I set the colour to black they look almost identical. I feel as though I've tried most things to try and change but have been unable to do so this far.

Any help would be much appreciated - I will leave a screen shot for better reference.
