Biotechnology colors are a simple but powerful way to classify the diverse applications of biotechnology across medicine, agriculture, industry, environment, food, marine science, ethics, and safety. Instead of seeing biotechnology as a single field, the color-based classification system helps students, researchers, and policymakers quickly understand where and how biotechnology is applied in real life.
What Are Biotechnology Colors?
Biotechnology colors are an informal but widely used classification that groups biotechnological activities based on their sector of application.
Each color represents a distinct domain, making complex biotechnology easier to understand, teach, and regulate.
