The reason that internetoutboards does not use that description is because it is incorrect. The paint was originally called charcoal/gray or simply gray(what the color actually is) and was later re translated to English and then changed to silver/gray(which it is not). The silver/gray was originally used on the pre 1993 model engines which had a cobalt blue frame and silver/gray covers. When Tohatsu stopped selling the original cover silver/gray they switched the name to the 2000-2005 engine paint color....Confusing and stupid
The aquamarine color is actually midnight blue in shade, not aquamarine....Also confusing and not bright
As to the codes, they aren't used. Hence the trouble finding them. Dealers buy the paint as a part number , not a paint code. Tohatsu obviously has a code but, they aren't telling because they want you to buy the paint from a dealer. However, any paint shop can color match by computer if you take in a sample.
