TECHNICAL EXPERTISE & METHODOLOGY

Frequently Asked Questions

Why does the Live UI Mockup adapt to my palette background?+

A complete palette defines both structural surfaces and interactive accents. In Palette Native mode, the studio uses the tones in your active palette as the actual container, hero, and card surfaces, calculating strict WCAG 2.1 relative luminance for 100% legible contrast with no uninvited default white.

Can I customize which swatch powers which UI surface?+

Yes. Use the Theme Preset buttons or the custom surface dropdown selectors to instantly assign any swatch from your palette to the Canvas, Hero banner, and Feature cards.
