A Google search on the fading tendency of inks versus acrylics
suggests tube acrylics purchased in an art supply store will retain
their color for decades, if not centuries. This is based on expert
commentary on a number of websites. Cheaper craft acrylics, I
suspect, would be more like ink in that they can fade noticeably
in just a few years.
To restore the look of the rock wall (1), I'd get some artist tube
acrylics and mix up some washes. Make sure the wash has no
paint sediment in it. Use gentle plant misting spray bottles to
mist on the washes. In addition to a black wash, consider wash-
ing the rocks with other colors, like brown, blue-gray, or yellow-
tan, depending on the scene you're modeling.
Then you could mist the various washes on your rock wall to
restore the vitality of the color. Several passes will probably
help a lot.
