Colorblindsafe Symbol Patterns

Create seamless symbol patterns that stay clear in grayscale and common color-vision conditions. This prompt uses distinct silhouettes, textures, luminance, and spacing so meaning never depends on color alone. Ideal for inclusive packaging, education, wayfinding, healthcare, stationery, and brand systems. Provide only a pattern brief and style brief; the prompt handles repeat continuity, small-scale clarity, and accessibility checks.
