Drop in a photo. Give it a line. We'll make it billboard-shaped and just a little bit wonky. Build a billboard, put your idea out into the world, and make it count. Every creation joins the gallery for curious people to discover. Send us the thought you can't stop thinking about. It might be the next thing lighting up the road.

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.

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
