Here it is now.
176051 in my barn is a 16' 1966 Guide with GS Green. I've attached two photos. The GS Green is flanked by Kirby's Blind Green. The Gs Green is origional as it is a one owner boat and there are no signs of any prior canvas work. ie. no extra holes. Blind green is the closest shade from the Kirby color chart. Computers being what they are you may have some color variation BUT the Blind Green can sort of set the bar.
