I think the relationship with ambient light may be important, but shouldn't the trend have gone the other way for the latter 19th and early 20th centuries then?

I think the relationship with ambient light may be important, but shouldn't the trend have gone the other way for the latter 19th and early 20th centuries then? As more people shifted from being involved in some form of agricultural or other outdoor manual labor to factory and office jobs, wouldn't we have seen a greater demand for bright colors as people spent more time inside?
