Color Theory No. 2

Good morning friends!  Today I have the next post in my color theory series to share with you.  In the first post we talked a little about the color wheel, and today I would like to talk about color harmonies.  Color harmonies are different colors within the color wheel that create a pleasing effect to the eye and are grouped by their location in the color wheel.  Today I wanted to illustrate complementary color.  Complementary colors are two colors that sit opposite of one another on the color wheel.  A few examples are yellow/violet, red/green and blue/orange.  I chose to do the complementary colors, blue and orange, and I have showed you an example below.  In this picture, the artist only used tints and shades of blue and orange to display their art.

What do you think of this color harmony?  Do you like these two colors together?  Do you think they create a pleasing effect?
