Refering to camouflage colours, the WNr 170096 belonged to very first of Me 262 series, when RLM74/75/76 scheme was appiled. The most known aircraft of this batch was WNr 170056 (V056) with FuG 218 radar antenas - the colour photos shown her in grey shades. IMHO the grey camouflage of 170096 was simply darkened with dark green spots.
