1/700 ship , (very small) RUSSIAN CRUISER " KALININ " HELP !!

YES , 1/700 is small ! I still want to do a credible job on this ship . The ship has P.E. from WHITE ENSIGN MODELS . and paint by moi . NOW , the thing is NO one seems to know what color to paint them ! From the box pictures she,s a grey green on the side panel . She,s a light grey on the picture on the top . TRUMPETER is good at that ! Now , do I use a mix of light ghost grey mixed 50-50 with dark sea grey ? Or do I use light sea grey with a drop or two of green ? No seems to know  , as like the JAPANESE in WW2 they were painted differently wherever they served . That,s like the deck .On the box top it looks like " Wood Tan " and on the side panel (overhead view) the deck is an orangey tan . This is the only RUSSIAN ship in my collection . I do want it to be right . HELP.            tankerbuilder
