Help me design a logo for my coffee mug company, ya mugs!

Keep your coffee comfortable.

Kunst en ontwerp

I am interested in creating a logo for an online company I'm starting called Ceramik Mugs. I've recently moved to the Bay Area and have become preoccupied with the coffee scene here. On the weekends, I like to go try out new coffee places, especially those that roast their own coffee beans. To see the coffee, in essence, being made, adds a whole new dimension to drinking coffee. I'm not a coffee snob yet, but talk to me in a few months, and I most likely will be! Anyways, I was at a coffee shop in Portland, Oregon and bought one of their mugs. It was thick, ceramic and I really liked the feel of it in my hands. I went online to look for more like this and couldn't find any stores dedicated to just selling mugs of this type (or really mugs in general, you either are buying them in bulk or buying them from some store or as a souvenir somewhere). So, I'm going to start an online company that specializes exclusively in selling ceramic mugs, with a portion of the price paid for the mug going to charity (although the percentage of the price has not been set yet). My market is coffee-connoisseurs/"hipsters." As far as the style goes, I want the logo to have the feel of someone drinking their coffee in the forest (I know this is very subjective, and so if it doesn't make sense, disregard.) Also, I want the logo to feel somewhat nostalgic, but not too much - still want a touch of the modern. Another note: if you could have a few designs with a mug in it, that'd be great. I'll attach a picture of the type of mug I'll be selling below (don't include the logo please - I own no rights to that logo.) Also, please do not include the slogan in every design. I'm not sure yet if I will use it as part of the logo and may end up putting it somewhere else on the website.

I'd like to explore the following colors: Yellows: Energy, intellect, fun and youth. Dark neutrals: Formality, mystery, exclusivity and luxury. Let designers make suggestions:
