Colors work together in different ways.
There are basically two types of relationship between colors – harmony and contrast. Colors that are next to each other for example red and yellow, are harmonious, while those that are opposite, for example red and green, contrast with each other. Harmonious colors are more calming, and contrasting colors are more dramatic.
In this handmade necklace I used different shades of green (forest green, light green, mint green) and added little bit drama with contrasting color root beer. For background I had chosen neutral color cream, added shine and texture with copper beads.
In this modern, abstract painting I had chosen harmonious, calming colors: blue, blue green, green and added warmth and balance to painting with contrasting color yellow ochre.
