Pretty sure that the figure should not have a degree symbol in front of the K (for kelvin).
Incorrect color placement edit
This (currently widely used on WP) 2005 graphic is incorrect. For instance, it shows the blackbody curve going through green! And failing to go through white. Someone had broken color code - there used to be a lot of that out there. It looks like the white point math was done incorrectly, shifting the colors downward. My fuzzy recollection is there was a high-profile open-source library and web page with that bug in the early 2000's, which repeatedly burned people. Fyi, FWIW.
