Harmony and Contrast

It was interesting to know about the balck and white contrast, creating the color harmony. 

The colors that are next o each other can work together and in harmony. Blue and green are in harmony.

The colors that are opposite in color wheel are contrast. For eg; orange and purple are in contrast.

Black and white can be used to show strong contrast. Not in color wheel, but they are neutral colors. Black is darkness and white is like light.

Until God created the heavens there was only the void, which was all black with nothing, like the black paper. Then God created light and heavens and earth.He gave light to the void like the white of the chalk .
