Little Red Express truck paint code?

[RTDaddy]

Anyone have the factory paint code for a 78 or 79 Little Red Express truck?  Helping a buddy build an "Ol' red Express" out of a 57 Dodge truck.  Any leads appreciated.

3442-Bright Canyon Red comes to mind.
The car line has a color using the same name with code RR4.
This is from the '78 data book.
