# Soft UI

DS056. Aesthetic: Surfaces. Page: https://ui.codeatlas.com.br/atlas/soft-ui/. Index: https://ui.codeatlas.com.br/llms/atlas.txt

Rounded surfaces and delicate transitions for a welcoming feel.

- Status in 2026: Active. In current use.
- Trend 2027 to 2030: Rising (an editorial projection, not a forecast).
- The term: Community or market label, or a descriptive term.

## Traits

- radii
- subtle shadows
- pastel

Typical settings: Wellness, Consumer apps.

## When to use it, and when not

Consider it when the task and motivation match: people looking for a friendly experience. Typical settings: wellness, consumer apps.

Be careful when the risk below would hurt the main task: low separation between elements.

Audience (a hypothesis about motivation and task, never measured, not a statement about any group): People looking for a friendly experience.

## UX risk and how to reduce it

- Risk: Low separation between elements.
- Mitigation and accessibility: Reinforce outlines and states.
- How to check: Test a prototype against a plain baseline on a real task: completion, time, errors, comprehension, accessibility and preference, segmented by context rather than by stereotype.

## Evidence

Indirect: the sources support underlying principles, not a preference for this style.

The sources support the principles that apply to this term. None shows that this style works better or is preferred.

- [E07] W3C Web Accessibility Initiative (2023). WCAG 2.2: How to Meet WCAG (Quick Reference). https://www.w3.org/WAI/WCAG22/quickref/ (Standard or guideline). Does not support: What users prefer or what performs better. A standard says what is required, not what is popular.
- [E11] Google Design (2025). Expressive Design: Google's UX Research. https://design.google/library/expressive-material-design-google-research (Preliminary). Does not support: Independent replication. The studies are the vendor's, the data are not published on this page, and the result concerns their own design system.

## Limits

- The atlas is a broad, living catalogue, not every style that exists. No authority enumerates them, and the classes (movement, aesthetic, design system, layout, pattern, principle) overlap.
- The 1 to 5 scores are relative editorial judgements. They are not results of a study and not a measure of quality.
- An audience is a hypothesis about motivation, task and context. It was never measured and says nothing about any age, gender or other group.
- The sources support underlying principles (visual complexity, legibility, grouping, accessibility, platform conventions). None shows that a particular style works better or is preferred.
- The 2027 to 2030 trend is an editorial projection, not a forecast.
- Terms in the Future / AI category rest on exploratory work, some of it preprints, with no causal validation.

## Heuristic scales

Relative editorial judgements from 1 to 5, not results of a study.

- Visual complexity: 2 / 5 (heuristic)
- Expressiveness: 3 / 5 (heuristic)

```text
Design this interface in the "Soft UI" direction (aesthetic, surfaces): Rounded surfaces and delicate transitions for a welcoming feel.
Visual and interaction traits to use: radii, subtle shadows, pastel.
Main UX risk: Low separation between elements. Mitigate it: Reinforce outlines and states.
Keep it accessible to WCAG 2.2 AA: contrast, visible focus, keyboard operation, 24 px minimum targets, reflow at 320 CSS px and reduced motion.
Keep the content, hierarchy and behavior the same as a plain baseline so the two can be compared. Do not claim the style performs better; the choice should be validated with users.
