I wanted to keep part of the feel of each company to maintain their brand equity, considering they are both big names. Since Nikon's products and branding rely more on their color than EMS', I decided to keep Nikon's yellow. Each of the logos use similar diagonal lines, so I used similar diagonal lines to hint at each. Finally, I decided to go with a typeface similar to the EMS logo because it seemed more recognizable than Nikon's. The supporting text makes the logo work in a system where it can denote a department or tagline (like the green initiative logo).
For the green initiative logo, I wanted to go green without being the color green. I also wanted to avoid explicitly using a leaf shape. I also wanted to maintain the diagonal lines from the original merger logo. After many iterations and much research, I came up with this aspen leaf logo. The aspen groves are some of the oldest organisms in the world. I wanted to hint at the size and legacy of the Nikon company. The aspen also has a perfect, iconic yellow color in the fall. I used only half of the leaf because the whole thing was distracting and felt awkward and cliche.
