I have been having an issue tracking down polly scale concrete for my bucket. I even lucked out at my local hobby shop and was able to pick up some PPR brunswick green, PPR Maroon and reefer yellow. I had to special order the caboose (and I think its custom due to the fact that the image was just the color sample and not the bottle). I know my options for concrete are to use the humrol combo or have the color made up but I was wondering if anyone has found a suitible equivilent. On hand I have a ton of vellijo colors for painting minuatures including a wide range of tans (desert grey, khaki, field drab, tan earth). The closest match visually (as far as i can tell comparing the color to images) is vellijo khaki grey but it seems a little dark. The color sample below is faily close to how the paint looks dried.
