Within the ‘Asset Gallery’ it is possible to filter images based on a color. This can be done in 2 ways. In this example you see 3 uploaded images, 2 of them contain a green color and the third one contains a red color.
The first way is to select an image and find the ‘Color palette’ on the right. Click on one of the colors to search all images which contain that color. Brandifyer will show you the results. In this case, that would be the 2 images which have been just uploaded.
