Pepkio Bio-Safe Palette Tester

Evaluates scientific figure color palettes for colorblind accessibility, grayscale legibility, and perceptual contrast using CIEDE2000 color difference metrics. The toolkit performs spectral simulations for protanopia, deuteranopia, and tritanopia, detects low-contrast swatch pairs, and computes automated CIELAB hue and lightness adjustments. An interactive browser application enables visual inspection of palette swatches across color vision deficiency models, while Python and JavaScript client packages integrate palette validation into automated plotting and publication figure pipelines. Analytical algorithms run on central servers, and clients submit palette definitions to retrieve diagnostics, contrast matrices, and exportable code snippets.
