It occurs to me that any weathering due to citrus might (would?) be considerably
different from just about any other weathering process we might want to simulate.
I'm guessing - but don't know - that citrus peel and/or juice would be a 'cleaner'
first but weather to a medium brown.
I'm also trying to figure out "what color are lemons (or oranges)" when being
shipped in bulk in open gondolas? I suspect that a variegated yellow that has
some brown/dark over tones would be more like the prototype than a simple
overall bright yellow?
