Paul Gunder is the founder of Rocky Mountain Apps, where he builds free calculators, generators and reference tools. He is not a professional color scientist or a certified accessibility auditor. On ColorPlum his job is to make sure every value comes from a named source, every conversion and contrast figure follows the published CSS Color 4 and WCAG 2.2 formulas, and each page explains in plain language what the numbers mean and how to use them.
