Here is a new idea I came up. I am still thinking along the lines of a clean letterform, since your logo will often end up on tags and smaller things. The colors reflect the corresponding initials inside of the letterform. Both work great together, or as separate icons/wordmarks. Let me know if you would like to see it in any other colors... Thanks!
As you can see, it is a very flexible/versatile logomark--making color changes easy & keeping print and production costs low. It looks great on any color.
