I made a slight modification to the previously posted heralds. It's color comes in between the two earlier ones and more correctly matches the CMQ herald color
I also found the CMQ decals and the correct paint colors at Highball Graphics. Since most of the decal is here maybe getting the herald and road name printed won't be so bad.
The paint scheme looks like this.
They suggest Tru Color TCP-84 Maersk Blue and TCP-121 Mo PAC Eagle Gray.
I have ordered the decals and will get the paint soon. I guess learning how to paint and decal is finally rising to the top of my list.
