Prompt an interface into existence and a familiar set of choices arrives with it: neon at full saturation, glow that decorates nothing and emoji standing in for icons. Seven specimens are reproduced below.
Neon with no hierarchy
Electric blue beside hot pink beside acid green, every one at full saturation. A palette works by making some things recede so others can come forward, and this one skips that step entirely.
Dark mode with decorative glow
A radial haze blooms behind the content. Nothing in the interface emits light, and the glow does not track any state or interaction. Glowing dark interfaces are common in the training data and the model reproduces the average.
Emoji doing an icon's job
A rocket for launch and a lightbulb for ideas, pasted into navigation where a designed icon set should live. Emoji ignore your palette and render differently on every platform, so the same nav bar ships in a different style on every device.
Purple gradients on everything
The indigo-to-violet wash is the single most recognizable artifact of generated UI. It imitates the successful SaaS sites in the training data so faithfully that it now signals the opposite of what those brands intended.
A card for every block of info
Containers inside containers inside containers, each with its own border and radius. A card marks a boundary, and a page where each block has one has no boundaries left to show.
Colored side tabs on every block
A thin accent bar down the left edge of each card, cycling through the palette. Ask what the colors encode and there is no answer: they do not track category or status, and the sequence restarts wherever the grid wraps.
Status dots that mean nothing
Green and red circles beside list items, promising live state the interface does not track. Reload the page and they never change, because there is nothing behind them to change.
