Dave, I made mine in "the White" so I guess the pigment is a far gone conclusion but I would go with the Spanish brown the next time. I may have used more BOL/Mineral spirits than necessary in my process because I soaked the whole tarp in it,drained back what I could but for a 9'x12'tarp there was only about a coffee can left out a gallons of each component. I trimmed it down to an 8'x8' that still needs some work to be done reinforcing corners and adding tie downs but I could use it as-is if necessary. Baker's books are a good source but sometimes I catch things I missed or misunderstood from a video. As with some things, his videos may become as hard to get as his book "The Trackless Forest".
