Mac

Generate precise color patches and calibration patterns, and drive them remotely via PatternSpace Remote, ColourSpace, CalMAN and PGenerator with advanced HDR output. PatternSpace is a professional test pattern generator for display calibration on macOS. Use it to show precise color patches, reference patterns, and calibration targets on the exact display you want to measure. PatternSpace is built for color-critical work where repeatable output, clear controls, and fast switching between patterns matter. Free on macOS: - A built-in library of solid patches, color bars, grayscale ramps, clipping targets, gamma patterns, geometry checks, swatches, and calibration references. - Device Native, Display SDR, and the full set of SDR Reference presets (sRGB, Adobe RGB, P3, BT.709/BT.1886, BT.2020, DCI, and more). - Full and Legal measurement range, output diagnostics, and detailed display and profile information before you measure. - PatternSpace Remote server — discovery, status, and up to 25 rendered patches per session to drive PatternSpace from your own scripts and tools. PatternSpace Pro (one-time in-app purchase) adds: - Unlimited PatternSpace Remote rendering. - ColourSpace, CalMAN, and PGenerator network automation, so calibration software can drive patterns directly. - Advanced HDR output: HDR PQ, system-tone-mapped HDR, Display HDR, and Linear HDR presets. - Peak White and EDR control for HDR measurement. PatternSpace is designed for calibrators, display reviewers, video engineers, home theater installers, and anyone who needs reliable test patterns for measuring and tuning screens. The manual pattern library and free PatternSpace Remote evaluation are included at no charge. PatternSpace Pro is a single one-time purchase — no subscription — and can be shared with Family Sharing. ColourSpace, CalMAN, and PGenerator are trademarks of their respective owners.
