24 alternatives to Draw a map and let it be colored – Four color theorem demo
This interactive tool lets users draw lines on a canvas to create map regions, then applies an automated coloring algorithm based on the four color theorem. After drawing, users click solve and the application colors… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

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'm making a coloring book of data structures and algorithms for programmers and students. So far I have a prototype page for a sorting algorithm (albeit a rather simple one). Here the Selection Sort coloring pages you can print. https://coderscoloringbook.com/selectionsort And here is how I colored mine. https://coderscoloringbook.com/selectionsortcolored A coloring book is not quite enough to teach algorithms on its own, but I really get a lot from visual reinforcement of what I learn from books/lectures. Do you think having coloring pages like this could…

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

In 2023, I tried building dynamic color theming by programmatically rotating HSL values. The results weren't good—garish combinations, inconsistent luminosity, completely unusable for UI work. That kicked off a two-year (sporadic) rabbit hole into color theory like Josef Albers' "Interaction of Color," perceptual color spaces (OKLCH vs sRGB), and effects like Bezold-Brücke. I learned that programmatic palette generation is genuinely hard. Nothing beats a trained eye. But I carried on anyway and made the Color Palette Pro. What it does: It generates 6 palette types (analogous, complementary,…

Creating high-quality scientific figures can be time-consuming and challenging, even though sketching ideas on paper is relatively easy. Furthermore, recreating existing figures that are not stored in formats preserving semantic information is equally complex. To tackle this problem, we introduce DeTikZify, a novel multimodal language model that automatically synthesizes scientific figures as semantics-preserving TikZ graphics programs based on sketches and existing figures. We also introduce a Monte Carlo Tree Search-based inference algorithm that enables DeTikZify to iteratively refine its…
