Use this tool when you need to ensure color-vision accessibility in images or palettes, as it checks for colorblind safety and recolors them to simulate protan, deutan, and tritan vision. It takes image or palette inputs and outputs colorblind-safe assessments and recolored visuals via local stdio. Ideal for designers and developers who want to verify their work is accessible to colorblind users.
