I'm in despair! I'm in despair that I'd be released in this color!
To celebrate the rerelease of Nendoroid Zetsubou-sensei, a special version featuring colors selected by the original manga's author, Kouji Kumeta, is being released as 'Nendoroid Nozumu Itoshiki 1.5: Kouji Kumeta Color Ver.'.
It might not be the same Zetsubou-sensei you're used to, but the colors were selected by Kouji Kumeta himself! The Nendoroid itself is exactly the same as Nendoroid Nozumu Itoshiki 1.5 - just the coloring is different.
