If a chemical is rated high in health, flammability, and reactivity, which colors would show high numbers?

The symbol system used to rate chemical hazards assigns blue to health hazards, red to flammability, and yellow to reactivity, with a 0–4 scale where higher numbers mean greater danger. If a chemical is high in all three of these categories, you’d expect high numbers in blue, red, and yellow. The white area covers special hazards (like oxidizers or radioactive materials) and isn’t part of the health, flammability, or reactivity ratings, so it wouldn’t show a high number for those categories. Therefore, blue, red, and yellow are the colors that would indicate high numbers in health, flammability, and reactivity.
