The logo for Tesla Motors is easily my favorite car logo because of the wordmark design as well as the brandmark. The simple design is easily recognizable. The sharp points contrast well with the curves of the logo.
The FedEx logo is one of my favorite logos because of its simplicity. It is a simple wordmark design that also contains an arrow that is formed between the E and X. The color scheme of purple and orange is also very appealing.
The Amazon logo is the final logo that I am personally drawn to. Much like the FedEx logo it contains a hidden message in its design with an arrow pointing from A to Z referencing their wide range of products. It is a simple wordtext design but the basic black and orange color scheme is very appealing to me.
