A custom-designed font (based on Futura) has been skewed and distorted to give the font a whimsical, fun, friendly and fast feeling. Think of bottles rattling around in a truck on a bumpy road. Blue and green was well suited to the industry and communicates ease of use, friendliness to the environment, and technology. The handwritten 4 gives the logo a sense of motion and stands out to remind people that it’s a number and not the word “for”.
