A second proposal for the colours my protogen sona. A bit more generic, I was thinking that they'd have stealth/espionnage purpose à là Soundwave in Transformers. I used a different base too. The pattern in the armor reminded me of the saiyan armors so I tried something there, not sure about that brown tho.
oh I found a way better version of this base sheet
