What it does
Umbra brings a designer-quality dark mode to every website. Instead of harsh color inversion, it uses carefully balanced colors that are easier on the eyes. It automatically skips sites with native dark themes, reduces white flashes while pages load, and lets you customize brightness, contrast, and grayscale globally or per site. Everything runs locally—no login, no tracking, and no personal data collection.

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…
