Description

How could the content be improved?

Our instructor selected the color channels out instead of multiplying the others by 0 when he plotted the red, green, and blue channels separately. From what I could tell, the way the lesson is written with multiplying the other channels by 0 it inverts the colors when plotting, where the light red is dark red and vise versa and the selection method doesn't do that. Maybe should switch to selecting the channel instead of multiplying by 0's?
