about the color so that way you do have to understand that hey if you have a tree you know the leaves are green and like the bark is brown so you have to identify some of the objects and try to like learn features about like edges and so on so so so that's the goal of this this line of work so it's best visually illustrated here so grayscale so an image can be just like you have RGB there are like various different color channels parameterizations of an actual image and instead of using the RGB color space you can use the L a B color space
