Yellow.

Yellow is the king of the color scheme. This is a king with character who does not tolerate violation of his rules. 

There can only be one king, which means he won't tolerate another shade of yellow (or you'll get a neon sign instead of armor). 

Every king rules by force and the king's strength lies in his army - in the base coat.  If it is bad, incomplete, or does not match in shade, it will not help its king in any way. The right shade and value of the base coat allow the Yellow bend surface, make the round angular and vice versa.

A king wouldn't be a king without his people, and our king's people are shadows. If the shadows are pale, we'll have a pale king. If the shadows don't match the lighting, we'll have a ridiculous king.  But if the people match in hue and tone, the king will shine. 

It is the people who make the king. And they are the ones who overthrow him. Never let people near the king; his guards must always be between them.

A king is always surrounded by his court. A wise king keeps only those who help him shine even more. The king is the center of attention; no one around him should be brighter or lighter. If our king is ochre, then all the other supporting colors should be darker.

You just need to remember:

Yellow is the king, you can't have too much of it.

Brown is the guard. It always separates the king from the people.

Purple, violet, green, red, orange, grey - People of shadows. But never blue or black color. Blue light render yellow black. And it's impossible to have black shadows outside the open space.

Any colours for small details - court. But always darker then The King.

All hail the King.
