A triadic colour scheme is used in this illustration, the colours blue, purple and orange that are evenly spaced around the colour wheel. Triadic colour harmonies tend to be quite vibrant, even if you use pale or unsaturated versions of your hues.
I'm an illustrator Aeppol who is painting little happiness in our daily life and small special things that we easily pass by. This is the diary of a forest girl. You can find my previous illustrations of simple everyday moments here.
