Make your logo extra bright on HDR screens
Certain logos started standing out to me on LinkedIn as brighter/whiter than everything else around them. I dug in and found out this is accomplished by adding a gain-map to an existing JPEG, visible only on HDR screens like a newer MacBook Pro. LinkedIn is the only social network I've found that isn't stripping them out, but of course you serve them up on your own site. I worked with Claude Code to turn it into a little browser-based utility (no registration) and hope you find it useful!
In plain words
This free browser tool converts logos into HDR JPEGs by adding gain-maps that make selected colors shine up to 7.5 times brighter than white on compatible screens, while remaining normal JPEGs everywhere else. Users upload a logo, choose which colors should glow, and download the result—no registration required. It's designed for designers and brands who want their logos to stand out on HDR displays like newer MacBook Pros, particularly for use on personal websites where gain-maps aren't stripped out like they are on most social networks.

Free tool: upload a logo, choose which colors should glow, download an HDR JPEG. On HDR screens the chosen parts shine up to 7.5× brighter than #FFFFFF — everywhere else it's a perfectly normal JPEG.
Upload a logo, choose which colors should glow, download an HDR JPEG. On HDR screens the chosen parts shine up to 7.5× brighter than #FFFFFF . Everywhere else it's a perfectly normal JPEG. Original artwork, converted with this tool. Drag the handle; on an HDR display in a capable browser the right side glows. “Use this” loads the original into the tool above. White type on black — the classic case. The whites are selected automatically. A white ring plus one brand color. Whites and the blue are both pushed to the same peak. Cream type on dark teal — not white, so it's picked as a color. Light elements on dark backgrounds glow best. Your JPEG stays a normal JPEG. For the web we add an ISO…from soverybright.com

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
