Abstract: 
Only a few years old, the idea that kinematic building blocks of scattering amplitudes have the same structure and properties as the Lie-algebra color factors - known as color-kinematics duality - has proven quite fruitful. Although the origins of the kinematic Lie-algebra structure remains unknown, it has improved our understanding of non-planar gauge theory and gravity. In this talk, I will review the status of color-kinematics duality at tree and loop level, illuminating the open problems as well as the techniques for calculating non-planar Yang-Mills and gravity loop amplitudes.
