AI Style Generation

How to apply and regenerate color, typography, and visual treatment with AI — without touching your layout.

Layout and style are two separate decisions in Lega, and you can regenerate either one independently. This page covers style: the pass that decides colors, typography, and overall visual treatment.

Layout vs. style

When the AI generates a design, it's answering two different questions: where does everything go (layout — positions, structure, hierarchy) and what does it look like (style — palette, fonts, weights, decorative treatment). Keeping these separate means you can lock in a layout you like and try five different looks on it, or keep a style you like while restructuring the composition underneath it. See AI Layout Generation for the structural half of this pair.

In practice this means: if a generated layout has the right bones but the wrong mood — too corporate, too loud, wrong color story — you don't need to regenerate the whole frame. You can ask for a new style pass on the existing structure.

What a style pass changes

A style generation touches:

  • Color — the palette applied across shapes, backgrounds, and decorative elements, and how it's distributed (dominant vs. accent).
  • Typography — font pairing, weight, and size relationships between headline, body, and supporting text. See Text Layers for manual typography controls if you want to fine-tune after the AI pass.
  • Treatment — the overall visual register: minimal and flat, bold and graphic, soft and editorial, and so on. Prompt tone words ("minimal," "playful," "editorial," "bold") map directly to this.

It does not move or resize layers, change copy, or restructure the composition — that's layout's job.

Prompting a style regeneration

Style prompts work best when they describe a feeling or reference point rather than a literal spec:

  • "Warmer and more editorial" or "high-contrast and bold" give the AI a clear direction.
  • Naming a specific brand or product category ("feels like a boutique skincare brand") gives useful signal without requiring exact hex codes.
  • If you have brand colors or fonts saved, style generation will bias toward them automatically — see Building Reusable Brand Kits for setting that up once instead of specifying it per prompt.

For general design-language grounding — why certain palettes and type pairings read as cohesive rather than arbitrary — see AI Layout Generation, which covers the same underlying reasoning applied to composition instead of style.

When to use style generation vs. manual edits

Use AI style generation when you want to explore direction — "try this differently" — quickly, across the whole frame at once. Switch to manual controls (fill color picker, stroke, font selectors in the Properties panel) when you know exactly what you want changed and don't want the AI touching anything else. The two aren't mutually exclusive: a common workflow is AI style pass to get close, then manual nudges to finish.

Credits and limits

Style regenerations count as AI generations against your monthly usage, same as layout generations. See Understanding AI Credits & Limits for details on what counts and how limits reset.
