Weathering of white walls in the sunny south

[FCIN]

Well I sure don't live in the Vernon, CA, area, but wondering around the streets there in Google Street view, I sure see what you mean about the white buildings being WHITE. I guess about all I'd do, were I modeling buildings like that would be to give them a light spray of Lance Mindheim's india ink/alcohol spray, just to knock off the shine a little. Don't have the book close by, but seems like he mixes a drop or two of india ink in a quart size bottle of 90% alcohol and lightly sprays that over most everything, just to give an overall toned down effect.
