colour scheme

monochromatic- colour scheme
i have used a mint green shades (shown below) with a white colour which mixes well.the monochromatic scheme is not good as it makes it harder to identify the drawings at an original state 

analogous- colour scheme
i have used 3 main colours of red, yellow and orange with again a plain colour of white as well. however for this one i have used one shade of red (highest saturation) and with yellow and orange i have see different shades of the one colour (shown below)

complimentary- colour scheme
for this one i have chose opposite colours of red and blue. i have only used one shade of red at again a high saturation, however for the blue i have chose to use a variety of different shades(shown below)
