Might want to try a different color than red, as it may appear like patriotism. Also, the boldness of the red may not fit with what is a customer-support type of service. Our customer's business comes first, and we provide manufacturing for what they need.
For ranked choice #2, I like this because I can see it "building", perhaps on a website, which is neat for a company that does manufacturing. (The idea of building or manufacturing is not already in the name, unlike "custom" and "diagnostics".) Maybe the "Custom" comes in first, and then the "diagnostics". The arc looks like a creative "C", so that seems like it is customized. The shape of a C (the arc) is pushing left though, which might seem backward.
Entry #13 - I like the sense of partnership created here. And the fact that is looks like a person, makes me think of personalized, or customized. The person also tends to make me think of clinical diagnostics, which is good in that it is in medicine but may convey that Custom Diagnostics sells directly to doctors/clinicians, which they won't. (It's business-to-business)
Thanks for changing the color. However, I see my request was probably not quite right, as thi sintroduces a new color when there are already many colors. What I would like to see is the same concept but without the green -- for example, #31 with a blue like in the molecule
We talked as a team, and we like the direction of this concept. We would like to see it without the split color in the "Diagnostics". I think you were trying to show customization, but it might be too much.
