Symbol accessibility

Symbols must remain clear and meaningful for all users, regardless of their accessibility needs. Good symbol design considers various vision abilities and assistive technologies.

Accessibility requirements for symbols:

• Clear meaning with VoiceOver
• Sufficient contrast in all states
• Recognition at various sizes
• Meaningful color alternatives
• Support for increased contrast
• Labels for complex symbols

When users enable accessibility settings, symbols adapt automatically. Increased contrast mode makes symbols more distinct, while reduced transparency improves symbol clarity against backgrounds. Dynamic Type adjustments maintain proper symbol-to-text relationships.

Avoid using symbols alone to convey critical information. Always provide text labels or alternative indicators that work with assistive technologies.
