Use palettes with sufficient contrast without shouting. Provide a high‑contrast toggle that also adjusts link states and focus outlines. Avoid meaning encoded only in color. Test with tinted overlays and varying ambient light to ensure content remains readable when migraine sensitivity or visual stress spikes unexpectedly.
Animations should clarify, never distract or provoke dizziness. Honor reduced motion settings by substituting fades for parallax and removing auto‑scrolling. Offer manual play controls for transitions and carousels. People with vestibular conditions, ADHD, or sensory processing differences deserve agency over pace, rhythm, and visual complexity.
Unexpected sound startles and drains focus. Start quiet, allow opt‑in alerts, and respect device accessibility settings for loudness, vibrations, and balance. Caption everything, describe audio cues, and provide transcripts. Colleagues with auditory sensitivities report calmer collaboration when notifications whisper instead of shout and tactile nudges can be muted.
