Ahem...
In case you did not know this, real rocks and stuff are outside in the sunlight and the fade all of the time. Rocks facing south will look different than rocks factin north. Utility poles be gray and weathered facing north (into the wind and the ice) but more pristine on the south side.
LIONS do not worry about the perfections of the colors. Even roling stock, may come out of the shops just perfect, but in a fe years the paint will be faded and will not match anybody's color chips.
If you want to recolor a rock, and it will not take your paint because of a sealer, just put a light dusting of new plaster over the top of it, and that should give you a new base to work with.
Fortunately, the LION models SUBWAYS, and so dirty tunnels are jus plain old dirty tunnels, and need not much more decoration.

Thanks for your post with observations. When I first started in MRR 10 years ago, I had flourescent lighting over head...it was in place already. I was warned to beware the UV problem associated with floursecent lighting, and your image confirms it.
I have since gone on to use 35 watt GU-10 style wherever possible...pots on tracks. They produce UV as well, but it is apparently better controlled in the halogens. Next to a window, of course, all bets are off.
If you were to mask the area around faded ground foam, you could possibly touch up the colour with craft paints blended to the correct shade and sprayed either with a sprayer or an air gun. Mind you, damage done to colours on ground foam is probably going to be deep-seated in the rubber itself, and the ground foam may be largely fragile dust if you touch it.

There is a sleeve that you can get to go over your tubes that will filter out the UV.
I have the right to remain silent. By posting here I have given up that right and accept that anything I say can and will be used as evidence to critique me.

If I were you I would add the UV filter tubes you can get at your local hardware store.
Stop using the Realistic Water from Woodland Scenics, it is known to cloud up and crack in certain situations, use Envirotex or Magic Water (google).
You could use an airbrush and craft paints to touch up and blend the old turf and rocks with the new stuff.
