Chris Bennett built a tool that turns a logo into a gain-map JPEG, so the colors you pick shine up to 7.5 times brighter than plain white on HDR screens and stay a perfectly normal JPEG everywhere else. Light elements on dark backgrounds glow best. The page also shows how to paint text through such an image with background-clip: text, gated behind @media (dynamic-range: high).
Make your logo brighter than white
