The primary LinkedIn color palette is made up of three colors. LinkedIn Blue, the color on this page, plus black and white.

The palette can also include cool grays, with the three examples from their site shown below. I assume there are more than these three allowed, but that's just a guess.
There is also an accent color palette with colors that can be used to draw attention to specific elements. According to their branding guidelines they should be used in the order listed here, left to right.
There is also an extended accent palette that is built on these colors which you can see on the LinkedIn site.
