Color Palette ProNov 2025 · colorpalette.pro · ▲151In 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.

Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
