# De Stijl

DS005. Movement: Geometric Abstraction. Page: https://ui.codeatlas.com.br/atlas/de-stijl/. Index: https://ui.codeatlas.com.br/llms/atlas.txt

Organization into rectangles, orthogonal lines and basic colors.

- Status in 2026: Historical. A historical movement that still informs current work.
- Trend 2027 to 2030: Niche (an editorial projection, not a forecast).
- The term: Established historical name.

## Traits

- rectangular grid
- black
- primary colors

Typical settings: Portfolios, Arts, Catalogs.

## When to use it, and when not

Consider it when the task and motivation match: people drawn to geometric order. Typical settings: portfolios, arts, catalogs.

Be careful when the risk below would hurt the main task: rigid palette and fragmented content.

Audience (a hypothesis about motivation and task, never measured, not a statement about any group): People drawn to geometric order.

## UX risk and how to reduce it

- Risk: Rigid palette and fragmented content.
- Mitigation and accessibility: Preserve reading continuity.
- 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.

- [E06] Wagemans, Elder, Kubovy, Palmer, Peterson, Singh, von der Heydt (2012). A century of Gestalt psychology in visual perception: I. Perceptual grouping and figure-ground organization. https://doi.org/10.1037/a0029333 (Established). Does not support: Any claim about interface styles. It is a review of perception, not of screens, and says nothing about preference.
- [E10] Elliot, Maier (2014). Color Psychology: Effects of Perceiving Color on Psychological Functioning in Humans. https://doi.org/10.1146/annurev-psych-010213-115035 (Established). Does not support: A fixed color-to-emotion mapping. The review stresses methodological limits; do not read it as 'blue means trust'.

## 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: 3 / 5 (heuristic)
- Expressiveness: 4 / 5 (heuristic)
- Information density: 2 / 5 (heuristic)

```text
Design this interface in the "De Stijl" direction (movement, geometric abstraction): Organization into rectangles, orthogonal lines and basic colors.
Visual and interaction traits to use: rectangular grid, black, primary colors.
Main UX risk: Rigid palette and fragmented content. Mitigate it: Preserve reading continuity.
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.
