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.

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

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

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…
