The blood in the anime is pink due to the somewhat iconic status of the color choice in the game. This was originally to bypass Japanese censorship laws that would have heavily restricted the game's sales (equivalent to an ESRB rating of AO: "Adults Only," which prevents the game from being sold in stores) if the blood had been realistically red.
The voice actor for Monokuma, a character throughout the series, was the same voice actor for Kaoru in the anime "Ouran High School Host Club".
The blood in this show is pink to avoid getting a TV-MA rating
Naegi's English VA (Bryce Papenbrook) is the only one to also voice a character in the game. All the others have different VAs in the game. He also voices Nagito Komaeda in Danganronpa 3 and Super Danganronpa 2
In Funimation's dub, they replaced all the voice actors except for Bryce Papenbrook (who had worked with Funimation before on Attack on Titan one year earlier, and was available) as Makoto.
