Frequently Asked Questions
What is Material 3 Tonal Palette?
Material 3 creates a set of 13 tones (0 to 100 lightness values) based on a key seed color. Tones are used across light and dark themes to ensure strict accessibility contrast ratios.
How does Swift Color extensions work?
The generated Swift code adds an extension to the
Color struct in SwiftUI. This lets you declare custom colors in code using hex strings without registering assets catalogs.Are contrast ratios calculated?
Yes. The lighter containers and text colors are mathematically derived from standard HSL offsets to verify text stays legible against the primary background tones.
Does this tool run offline?
Yes, 100%. Color calculations, hex parsing, XML/Kotlin code generation, and UI mockup painting occur completely locally in JavaScript.
