When the story is: public dashboards, exams, print in grey, legal slides. Skip it in cases like: relying on red/green alone to mean bad/good. Ishihara plates 1917; WCAG 2 contrast; Okabe–Ito palettes for deuteranopia redundant channels: position, pattern, label, not hue alone Yes if one claim is visible at a glance in Meta, Google and retail print; otherwise link to a full figure.
Yes for lab reports and poster boards if axes, units and a source line are present. Excel or Google Sheets or PowerPoint; export SVG/PDF. Do not rely on hue alone. Label directly and check greyscale. Accessible viz: honour redundant channels: position, pattern, label, not hue alone, and switch when relying on red/green alone to mean bad/good.
