There can be multiple colors. I would prefer not to have photos - I would like the design to be ameniable to silk screening with one or more colors. The type should be classy instead of bold or "in-your-face". I like artistic designs rather than, say block lettering. It would be nice to have something uplifting or rays of sunlight coming down from the heavens. Or God's Love pouring into people's hearts. Since there will be people from all over the world, a global partnership theme could work as well.
