Styles - changing one or two aspects

On the hotecommerce template there are 5 styles.

I like number 4 but i just need to change some of the font colours. Problem is if I click on custom it reverts to some random colours.

Is there a way to set the same colours in Style 4 into the Custom, then I can just change the one I want?

Thanks.

You can edit <template folder>/styles/style4.php
