Given the name 'US', we'd like it to follow some red white and blue theme. Subtle, but matching the name. Similar to Bank of America. Blue perhaps a bit darker.
Our Ideas and Additional Information:
As mentioned, Bank of America, but for medical supplies might be a good place to start. If there is a refined and simple way to convey shopping into the look, that would be ideal. Otherwise we are wide open to suggestions. See what sticks.
