I have looked a lot of places trying to find a color that looks like white pine for painting wooden crates. ALl the flesh tones and beiges have too much red. Finally, I just decided to mix my own. I feel pretty good about a 50/50 mix of Model Master's acrylic color Wood and Flat White. It takes a little more tweaking after the first mix but that's a good start. The Wood color by itself is just not realistic. Same for Humbrel's Wood color. The only time you would get wood that color is if you stained it. It's not too likely anybody was staining wood for crates. So, now I have my color for freshly made pine crates. In fact, I think I can use the basic combination for practically any freshly sawn wood. I'm open to other solutions.
Now, what are you using to replicate heavily weathered pine crates? They are going to have a lot of black in the color, but won't look anything like the greys offered in the standard paint colors.
