WCAG Shades vs Pattern Wallpaper Mobile

Use your camera to get a feel what WCAG's color contrast ratio. Any pixel in your camera feed that doesn't pass WCAG's guidelines for your chosen contrast color will get knocked out of the picture by Metal. You can also see contrast testing in live color blindness simulations (Machado et al.). The Web Content Accessibility Guidelines 2.1, which Apple recommends developers follow, sets a minimum luminance contrast ratio for legible text and icon states.  (To state the obvious, iPhone and iPad sensors do not magically quantify photoelectrons into absolute lumens. WCAG's heuristic is intended for screens, not whatever exposure bias you choose. This is a conceptual way to explore the guidelines IRL, not some shortcut to telling legal, QA or UX that you tested the latest release super quick... just go have fun.)

Pattern Wallpaper is an application that generates wallpaper using 2D tiled patterns. It contains hundreds of classic or trendy patterns, and the number is still growing. Each wallpaper supports personalized customization, including colors, rotation angle, line width, filling ratio, and other attributes. They also support parameter randomization, which can produce endless creative results. App features: - Pure code drawing, with ultra-high precision to reflect the details of the pattern. - A variety of attributes can be adjusted, including colors, rotation angle, line width, filling ratio, etc. Supports parameter randomization. - Supports exporting wallpapers of multiple resolutions at once according to the resolutions of the target devices. - You can mark favorites or add custom tags to patterns. - Mac/iPad/iPhone versions of the app are available.
