This is the USS Discovery NCC-1031 introduced in the originally prequel series Star Trek: Discovery. Later in the series the ship jumped forward in time to the 32nd century, and was refitted to that technology, and redesignated NCC-1031-A. This is the original configuration. The colors are based on the TNG uniforms, a variation of which is used by the 32nd century crew, but which are also more like the TOS uniforms. The original uniforms were all one color with no different colors used to signify different sections.
