This week, researchers at the Stanford Linear Accelerator announced that they have created an x-ray beam with two slightly different colors. The research was published in the Physical Review Letters on March 25, 2013.

Depending on their electronic structure, atoms and molecules can interact with light differently. Tuning the color of the x-rays will allow researchers to pick out specific atomic and molecular dynamics like how bonds break and rearrange in chemical reactions.
