Why is this function used
def comp(one,two):
for i in range(len(one)):
if one[i]!=two[i]:
return False
return True
Also i am not getting the final output its not showing the output image.

that function is just used to check the pixel values that if a particular pixel matches the required color.

I have updated the code for this.
