I'd guess more in the direction of first sale latency. Remarkable colors might fly off the lot, or they might moulder until they're dumped next year at a loss.

Grayscale palette doesn't invite a risk of emotional response introducing volatility to sales. Oddly enough, the models most likely to be available in actual colors fit the market most likely to care about resale value. Catastrophic depreciation hasn't ever seemed to impact luxury car sales. For excellent value retention, the other end of the market is where it's at. If MSRP for any trim level dips under US$20,000 it's certain to be available in bold colors. The other exceptions are the brand identification models - Miata, Supra, Mustang, Camaro - Emotional response is a desired outcome, so they're available in colors someone might actually form an opinion about.
