Hi Peter, sorry for the delay of my answer...
The colors are all Vallejo..
Here we are:

base color: a mix of 921 (english uniform), 983 (flat earth), 872 (chocolate brown), 948 (golden yellow), 913 (yellow ochre), 877 (gold brown) and 953 (flat yellow)
the shadow: adding at the base color ---> more 921,983 and 872
the light: adding at the base -----> 948 and 953 ...then only 948 and for the maximum light adding 858 (yellow ice)

I can't tell you the percentages because i don't remember...and also because i don't belive in the importance of a percentage, I think it's better to try to mix the colors until you find the tone you wanted to use for base and see how it responds by bringing it into the shadows and into the light ...
