WCAG 1.3.3: Sensory Characteristics
WCAG 1.3.3 requires that instructions for using content do not rely solely on sensory characteristics such as shape, color, size, visual location, orientation, or sound. This ensures that users who cannot perceive those sensory cues — due to blindness, color blindness, deafness, or other disabilities — can still understand and operate all features.
