In NFPA 704, which quadrant color corresponds to reactivity?

Explanation:
NFPA 704 uses a diamond with four colored quadrants to show different hazards at a glance. Blue is health, red is flammability, yellow is reactivity (instability), and white is for special hazards. The reactivity rating is communicated by the yellow quadrant, with numbers 0–4 indicating how reactive the material is under specific conditions. So, the color that represents reactivity is yellow.
