Usage guidance

Ambulance White provides a clean, clinical background. Blue Light is your primary colour for headings, navigation, and trust-building elements. Siren Red adds urgency for alerts, warnings, and critical CTAs. Hi-Vis Yellow works for badges, callouts, and elements that need to be seen immediately. Uniform Dark grounds body text with quiet authority. Use the red and yellow sparingly to maintain their impact.
