Hi there, I'd be pleased to work with you to build a great new logo, and I agree that simplicity is important here.
I have a background in working with engineers, and know how to translate science-speak. You mentioned four-color and full color, so I wanted to clarify- Do you mean spot color and raster? I ask, since full color is usually printed with four colors, and is called that. Are you also saying that yould like to specify that there are specifically four flat colors involved in the color version of the logo? Two is often what we see a lot of in logos, since three costs about the same to print as full color, and four spots are more expensive.
Thanks!
