Chromono turns your photos and videos black & white while keeping just one color vivid. Simply tap the part you want to keep, and anyone can create striking, cinematic, poster-like shots.

Made with Chromono

What you can do

• 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
• Brush spillover back to monochrome with the eraser
• Export in high quality at the original resolution
• Video color splash supported
• English / Japanese, light / dark mode
