Enfold – Customise Icons in Icon Box – colour and image

I am wanting to set up a section on my site using the icon box layout – 2 rows of 3 boxes. The layout is perfect but is it possible to have 6 specific colours for the icons or their background (either is acceptable)?

Also can I have custom icons (all have been created as vectors) – or is the an alternative way of creating this layout using graphics? I can illustrate exactly what I’m trying to achieve but am unsure if its possible to upload an illustrative screenshot on the forum.

Many thanks for your assistance

Andrew
