Sorry folks but unless you send a sample of the covering that you are using all the paint companies in the world will not be able to match your color...It's called dye lots and there all different...even the covering Mfg. run into this problem..Try it go to a hobby shop near you then go to one the other side of town and try to buy a matching roll of covering.
The solution take your covering to your local paint shop and have them color match it
