Greyscale Only
A full-screen generative colour artwork with a genuinely accurate eyedropper. Tap anywhere to sample the real pixel, but it reports greyscale luminance only and drops a grey swatch into a five-swatch palette. Copying, reordering and exporting the palette strip are free forever; the true colour values are the single one-time unlock. The artwork stays gloriously in colour the whole time, including behind the paywall.
