CoolPhoto：Color Walk人必备工具

This app is an essential color extraction tool for color walk enthusiasts. No in-app purchases, no monthly/quarterly/yearly subscriptions, and no ads. Extract photo colors and generate color palette collages with one tap. Supports Live Photos and still images. The app automatically extracts the dominant colors from your photo to create a custom color palette. It also auto-generates stickers via background removal and seamlessly blends them with the original image, giving ordinary photos a cinematic and design-forward feel. Within the app, you can adjust collage proportions, background color, sticker stroke color and thickness, font size, and font style. Fully local and privacy-protected — all processing is done on your device, with no data uploaded.
