This mark was inspired by the idea of protection, specifically through the use of a shield or barrier. A strong barrier is cast outward in a spiral movement from the center, to ward off and destroy microbial threats.
The soft colors keep the logo approachable in spite of intimidating technology will the rounded elements throughout the designs. Black and white are wonderful backdrops for more seriousness (black) and cleanliness of the environment this product achieves (white).
