The green can be found in WC delhezis, retros, and palmas I'm pretty sure. They do have tiny teeth.
Cb dels have green pigment too, it depends on substrate colour, diet and possibly a few other factors im missing.

only if they are high quality dels. It doesn't complete depends on the substrate, and food.
Pretty sure mine was a low quality. Had green pigment when i bought him, then it faded away over the light coloured tile. Once he was big enough to start accepting a wider variaty of foods the pigment started to come back. Then he broke his neck...
So i would assume almost any delhezi can have the green pigment depending on their environment and care.
