Gelcoat Products listed O'day Lt. Gray GCP code 29, and O'day Cream GCP code 30 when I asked them about the 192, which is all the same colors as a 222. Not sure about the blue sheer stripe, cove stripe, and boot stripe. Problem with Gelcoat Products they would only sell me a gallon for $100, and then an additional $20 to make a quart of gelcoat paste out of the gallon. This is for each color. $240+shipping is too much for me to fix a few chips...
If you search on the interwebs, you'll find a technique to approximate the color. If you can get a sample to a good paint store, they can scan it with a spectrophotometer, and tell you what their universal color formula is. They often do it with 6 colors... but if you only use the amounts they list for red, blue, yellow, black (typical gelcoat tinting kit colors) you should get close to the ballpark...
Let us know what you find out from Rudy at D&R... I should probably try and get some touch-up for mine, and hopefully he has some gelcoat in small containers, not just gallons!
