Chromono: Color Splash

Keep one color, gray the rest

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Chromono is a "color splash" app that turns your photos and videos black & white while keeping just one color vivid. Simply tap the part you want to keep. One color stands out against a monochrome world, letting anyone easily create striking, cinematic, poster-like shots — from photos and video alike. ■ Three easy steps 1. Choose a photo (or video) 2. Tap the screen to pick the color to keep (eyedropper) 3. Finish, export, and share ■ Features - Pick colors by tapping ("eyedropper"), or intuitively with the hue ring - Fine-tune the kept color's range and feathering - Layer on Crisp, Cartoon, or Painting styles - Clean up spillover with the Grayscale Eraser - One-tap "Compare original" to see before and after - Export in high quality at the original resolution - Video color splash supported (Pro) - iPhone / iPad, with light and dark mode ■ Great for - Creating stylish, share-worthy photos - Making a "signature color" pop — a red umbrella or blue sky in a black & white scene - Adding striking color accents to video, too ■ Pricing Chromono is free to use (ads are displayed). Purchasing the one-time "Chromono Pro" removes ads, exports without a watermark, and unlocks video color splash. Because it's a one-time (non-consumable) purchase, you can restore it after switching devices or reinstalling, as long as you use the same Apple ID. All photo and video processing happens entirely on your device; your edited data is never sent externally. Feedback, requests, and bug reports are always welcome at chromono.app@gmail.com.
