Which Paint Color for 1983 Evinrude 15HP Model E15RCTA

[CJB157]

I'm new to this forum and I'm looking for insight about paint color for my Evinrude. I just picked up an '83 Evinrude 15HP. When looking at the possibilities for touching up the blue paint, I found Marine Engine color charts list three possibilities for a 1983 model year. 1) Silver Blue part# 0777180; 2) Metallic Light Blue part #0777176; 3) Engine Blue part #0771243. The model number for mine is E15RCTA. Does anyone out there have any insight as to the correct color blue?

Thanks for your help.
