In the National Fire Protection Association 704 System of Identification, the diamond-shaped placard used for fire hazard is always colored:

Explanation:
NFPA 704 uses a color-coded diamond to quickly show different hazard types. Each color corresponds to a hazard category: blue for health, red for flammability (fire hazard), yellow for reactivity, and white for special hazards. Since the fire hazard is represented by flammability, that quadrant is always red. The central number (0–4) then indicates how severe that hazard is, but the key takeaway is that the fire hazard color is red.
