🎨 图片上色（单色着色 / 双色调）Colorize Image (Tint & Duotone)
给图片整体上色：单色着色模式按原图的明暗把整张图换成你选的颜色（类似 Photoshop“着色”），双色调模式把暗部映射为一种颜色、亮部映射为另一种颜色；强度可调，可批量处理多张图片，透明背景保持不变。图片只在浏览器本地处理。Colorize an image: Tint mode recolours the whole picture in your chosen colour while keeping its light and shade (like Photoshop's Colorize), and Duotone maps the shadows to one colour and the highlights to another. Adjust the strength, process several images at once, and transparent backgrounds stay transparent. Images are processed locally in your browser.

如何使用「图片上色（单色着色 / 双色调）」？How do I use the Colorize Image (Tint & Duotone) tool?
在「图片上色（单色着色 / 双色调）」中，选择或拖入文件，按需设置「模式」、「颜色（亮部）」、「暗部颜色」、「强度」、「输出格式」等选项，然后点击每个结果旁的「下载」按钮即可；有多个文件时也可以点「全部下载（ZIP）」一次打包下载。In the Colorize Image (Tint & Duotone): Choose or drop your files, set "Mode", "Colour (highlights)", "Shadow colour", "Strength", "Format", then click the Download button next to each result (with several files, "Download all (ZIP)" saves them together).
单色着色和双色调有什么区别？What is the difference between Tint and Duotone?
单色着色：先算出每个像素的亮度，再用所选颜色的色相和饱和度重新着色，黑色仍是黑色、白色仍是白色，中间调变成所选颜色，效果像老照片的棕褐色或单色海报。双色调：把最暗处变成“暗部颜色”、最亮处变成“亮部颜色”，中间按亮度平滑过渡，适合做海报、封面和社交媒体配图。Tint works out each pixel's brightness and repaints it with the hue and saturation of your colour: black stays black, white stays white and the mid-tones take on the colour — like a sepia photo or a single-colour poster. Duotone maps the darkest parts to the shadow colour and the brightest to the highlight colour, blending smoothly by brightness — popular for posters, covers and social images.
强度是什么意思？What does Strength do?
强度决定上色结果和原图混合的比例：100% 是完全上色，50% 是一半原图一半上色效果，可以只给照片轻轻加一点色调。Strength sets how much of the colorized result is mixed with the original: 100% is fully colorized and 50% is half and half, which is handy for giving a photo just a light colour cast.
黑白照片可以上色吗？Can I colorize a black-and-white photo?
可以整体染成一种颜色或做双色调，但这不是 AI 智能上色：不会自动识别天空、皮肤、树叶并分别填上真实颜色。Yes, you can tint it one colour or make a duotone, but this is not AI colorization: it does not recognise sky, skin or leaves and give each its natural colour.
