One-Click DPI Verifier
Reads intrinsic vs. display pixel dimensions to verify figure DPI requirements.
Colorblind Hex Validator
Test figure colors for colorblindness — simulate deuteranopia and protanopia for hex codes
Hex colours (one per line or comma-separated)

How it works
Uses the Brettel 1997 method to simulate how colours appear to people with deuteranopia (red-green, green-deficient) and protanopia (red-green, red-deficient). Pair contrast is calculated using WCAG relative luminance. Pairs below 3:1 are flagged.
