He took an average of 36 black and white photos per day thus for 21 day he took 36*21 = 756 black and white photos
He took an average of 60 color photos everyday thus for 21 day he took 60*21 = 1260 color photos
How many more color photos than black and white photos did Greg take on his trip?
1260 - 756 = 504 color photos
Greg took 502 color photos more than black and white photos on his trip.
