Check my brand colors and typography for accessibility

Check my brand style guide for accessibility and suggest fixes that keep the brand recognizable. Brand colors: [HEX codes and how each is used - e.g. "#FF6B35 for primary buttons"] Typefaces and sizes: [FONTS, weights, body and heading sizes] Where the brand appears: [website, app, slides, social, print, signage] Target standard: [e.g. "WCAG 2.2 AA", "AAA for body text"] Elements I'm worried about: [e.g. "light gray text", "white text on yellow buttons", "thin script font"] Check: 1. Color contrast: for every realistic text and background pair, the contrast ratio and pass/fail for normal text (4.5:1), large text (3:1), and UI components and graphics (3:1). If you can't calculate a ratio precisely, say so and tell me which checker to use. 2. Reliance on color: places where color alone carries meaning (status, links, charts), with alternatives that work for color-blind users. 3. Typography: minimum sizes, weights, line height, letter spacing, and fonts that are hard to read at small sizes. 4. Components: focus states, link styling, error and disabled states, and text over images or gradients. 5. Motion and imagery: rules for animation, flashing content, and alt text. Return: - A contrast matrix: Foreground | Background | Ratio | Normal text | Large text | UI. - Fixes: adjusted shades (new hex values close to the originals) or usage rules (e.g. "only for headings 24px and larger"). - An accessibility section I can paste into the style guide, with clear do and don't rules. Note that an accessible style guide doesn't guarantee an accessible product; test real pages with assistive technology and real users too.
