I hatched a Chimby just now and it hatched as the colour Orchid - isn't that a dye kit colour, are those hatchable?

I'm a newbie, so forgive, oh and not complaining, it's real cute.. x3 So I do hope I will be allowed to keep him/as this colour, he is just adorable as Orchid!

EDIT: was told that you can hatch orchid's during the Easter event.. c:
