Primes¶
- Color Harmony
- A common failure is either ignoring accessibility (creating beautiful designs that exclude users) or over-accommodating accessibility (creating monotonous, low-contrast designs that fail aesthetically)
This sourceW3C Recommendation. Specifies minimum color-contrast ratios (4.5:1 for normal text, 3:1 for large text and UI components at level AA) so content remains legible to users with low vision or color-vision deficiency; supports the accessibility-versus-aesthetic-intent tension. (Citation-fix: publisher corrected from 'Web Accessibility Consortium' to W3C.)

- Linearization-Meaning Mismatch
- In screen-reader accessibility, a richly laid-out webpage must be read aloud as a 1D stream, and the chosen linearization (DOM source order, with ARIA overrides) may or may not match the visual reading order the designer assumed — when mismatched, the page is technically complete but functionally inaccessible.
This sourceSpecifies meaningful sequence (Success Criterion 1.3.2) and info-and-relationships (1.3.1), where DOM/programmatic reading order must match the intended reading order, with ARIA used to reconcile them.

- Minimalism
- A common failure is minimalism that treats accessibility features as excess clutter to be removed
This sourceNormative guidelines establishing redundant signaling, sufficient contrast, and explicit labels as essential, non-decorative supports — a counterweight to over-aggressive minimalist removal.

Mechanisms¶
- Scroll Progression Design
- When the visual order and the source order drift apart, the meaningful sequence is lost for anyone not reading with their eyes, in direct violation of the accessibility standards that govern reading order.
This sourceRequires meaningful reading order to remain programmatically determinable for assistive technologies.
