For the images, are the RGB values considered(as f(x)) while calculating the norm?

Yes, it seems that it is the RGB colors that are considered since black is (0,0,0) as most of the first picture is darker while the second picture contains more red, (255,0,0) and yellow, (255,255,0).

Rather than use RGB values, we could possibly use cylindrical coordinates (like in a color wheel), to represent value, saturation, and lightness
