The TI-84 Plus CSE was released in 2014. It was TI's first color graphing calculator in the TI-84 lineup. Due to it’s poor performance, it was poorly received and replaced with the TI-84 Plus CE in 2015. This calculator contains the same processor as the monochrome TI-84 Plus and had to use more resources to power the color screen.
As a result of the poor reception, the TI-84 Plus CSE was quickly discontinued.
