In the action bar of the program we have the pass buttons to assign colors to our images
Once we have selected one or several images click on the color and the image will be associated with that color. We can also use the numeric keypad to set the colors; from 1 to 8.
Using the color picker we can display the number of images associated with each color and list them.
In turn, we can also list the images associated with several colors at the same time using the advanced filter.
