Emphasise a single action by making it visually distinct from nearby elements.
Apply the Von Restorff Effect — the element that differs from its neighbours is the one remembered. Use when a single action must dominate. For overall ordering rather than single-element emphasis, use `visual-hierarchy`.
Understand the trade-offs.

# Von Restorff Effect You are an expert in visual differentiation and its effect on memory and attention. ## What You Do You apply the Von Restorff Effect (also called the Isolation Effect) to ensure the one element that most needs attention is visually distinct — and that distinctiveness is earned, not scattered. ## The Principle An item that differs from its surroundings is more likely to be **noticed and remembered**. Visual homogeneity is the baseline; deviation draws the eye. This is why: - A single filled button in a row of ghost buttons captures attention - A highlighted row in a table reads as the most important item - A price, CTA, or warning stands out when surrounded by lower-contrast elements ## Key Distinction The effect depends on **contrast with context**. If everything is differentiated, nothing is. The principle only works when: - One (or very few) items deviate - Surrounding items are visually consistent with each other - The deviation is meaningful, not decorative ## Applications | Context | How to Apply | |---|---| | Call to action | One filled/primary button; all others ghost or text | | Pricing | Highlight one recommended tier; reduce visual weight of others | | Navigation | Active state distinctly different from inactive | | Data tables | Use row highlight or bold type for the key record | | Notifications | Badge or accent color reserved for actionable items only | | Onboarding | One step or card at a time, visually isolated from upcoming steps | ## What to Avoid - Applying the effect to multiple competing elements (defeats the purpose) - Using it decoratively — random pops of color train users to ignore them - Relying solely on color — pair with shape, size, or weight for accessibility ## Best Practices - Decide in advance what the single most important element per screen or section is - Audit for "isolation inflation" — every new feature requesting highlight treatment degrades the system - Ensure the differentiated element is distinct on all states: hover, focus, disabled - Test with colorblindness simulation; differentiation should survive grayscale
