Jumping ahead now by four colors.
Color #7 is a medium olive underbase, again mostly covered up by other colors. Mainly in the tall grass and trees
Color #8 is a medium green, prominent in the foreground and trees.
Color #9 is a dark brick red, with very little coverage; just a few spots and some texture here and there.
Color #10 is tan. It's most visible as a highlight texture in the foliage, and in the background at left.
The tan has just gone down in this pic. You can see some of the red scattered in the grass, and in exposed brick. The olive underbase is already nearly all covered up.
Color #11 is a darker green. Here's that state, as we print the next color.
