PhotoMat Exploration

Part of a project for a research group working on the development of new materials, mainly polymeric, using photophysical and photochemical tools. These symbols embody the concepts of light and synthesis, polymers, and particles.

The underlying overlapping shapes that make up these three alternatives are exposed here. The differences are subtle, but I think on the third option each color is represented more equally.

Which one do you think works better?
