Leonardo

What it does

Leonardo: an open source contrast-based color generator. Create beautiful, accessible, and adaptive color systems using contrast-ratio based generated colors.

Generate colors based on a desired contrast ratio.

Leonardo is a one-of-a-kind tool for creating, managing, and sharing accessible color systems for user interface design and data visualization. Charts and 3d models allow you to evaluate your color theme like never before. Choose from a variety of color spaces to create perceptually balanced color scales. Color swatches are generated by target contrast ratios so you no longer need to manually check contrast. Controls are paired with lightness inputs so you can also define your swatches by target lightness. Leonardo’s adaptive themes enable you to change the brightness, contrast, and saturation in less time than ever before. Download your theme or color scales as SVG files.

  I made a new AI colorizer2022 · palette.fm · ▲472

  Hi HN, I’m Emil, the maker behind Palette. I’ve been tinkering with AI and colorization for about five years. This is my latest colorization model. It’s a text-based AI colorizer, so you can edit the colorizations with natural language. To make it easier to use, I also automatically create captions and generate filters. Let me know what you think. You can see some of my results on my reddit page: https://www.reddit.com/user/emilwallner/?sort=top

  Talanoa▲346

  Hi 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…

  Angeldust – a fast and efficient video game▲716

  After years of solo development I'm presenting: Angeldust, an omni-compatible action RPG and building game! Website: http://angeldu.st My single server hosts 250+K active players in one giant, dynamic fantasy world. Angeldust's game server is pervasively multithreaded, implementing John Carmack's dream of processing an immutable world state each tick. Both world handling and network traffic routing uses any number of threads. For networking, a typical game session only uses ~3Kbps of bandwidth, enabling decent play even over 2G/EDGE networks. The client is programmed in C++…
