description The invention discloses an image color feature extraction method, device and equipment, and the method comprises the steps: obtaining a target image, inputting the target image into an image feature extraction model, and obtaining the color features of the target image; wherein the image feature extraction model is obtained by training according to a first distance between the color feature of the first original image and the color feature of the positive sample image and a second distance between the color feature of the first original image and the color feature of the negative sample image. The positive sample image is a positive sample image corresponding to the first original image, and the negative sample image is a negative sample image corresponding to the first original image. The color similarity between the first original image and the positive sample image is larger than a first threshold value, and the color similarity between the first original image and the negative sample image is smaller than
