The Digimon you are viewing now is categorized as a D-Project Recolor. These recolors come from the Digimon video game, D-Project. This game had an interesting feature where, when choosing a Digimon, you also choose which attribute you wanted it to have. This attribute change would also change the color of the Digimon. The reason these Digimon are not categorized as  Special Recolors is because, for the most part, the Digimon involved don't have a full blown color change, but more of a color tint change. Also, because certain Digimon who already have Special Recolors have different recolors in this game.

Nothing special about this Digimon.

The Digimon you are viewing now is a Redesigned Digimon. These Digimon are like complex Random Recolors, in that they were probably done unintentionally and have no unique information about them, other than looking different from its original. These differences usually go unnoticed due them not being mentioned in anything official. Sometimes a Digimon will have their design altered because of an artist's rendition of the Digimon.
