In fact, there is demand for colorful products. However, the way businesses measure demand today is through the aggregate unit demand. In effect, you get the lowest common denominator products rising to the top, and people with specific preferences can't get at their desired products. If instead, businesses would measure demand at a more granular level, they'd see this and be able to better serve their customers.

my startup varietyiq is working towards helping apparel businesses do this / have seen it work very well.
