@Johnwally I really like the inset box of your second design. The icons don't stick out very well on my slate gray background, so having a slight bit more emphasis helps.

Perhaps optionally invert the colours, too? A dark inset icon with a brighter link colour as the background "button" would stick out better on dark backgrounds.
