I went with something simple and easy to remember. 'C G' for the business name. The shape around the letters symbolise a coffee cup. And the line above symbolizes the crema that is typical of good quality coffee -- a trait the business wants to be known for among their customer base.
While I think black and white works best, the brief stated a preference away from green and/or black. Because of this, I included a blue and sand colour theme. Still memorable and works with the message the business is going for which is a reliable place freelancers can frequent to do their work.
Would really appreciate feedback and constructive critique! Thank you
