     Near 50% of specimens have brown tones in colouration but there are also vipers with green, grey, yellow, pink, orange and red tones. Zigzag is usually dark-brown but can be also black, dark-grey or dark-red, as well as bilineata and patternless specimens(most often females). The dorsal side of body is black or dark-brown, sometimes with small light spots. The tail have yellow tones with a dark underside. The head have more light colouration than the body and often have a "V" or "X"-like sign on the upper side. White or light-beige canthals and all or backside upper labials are typical for Vipera orlovi.
