The "ColorScheme"of a DistributionChart can be changed using the ChartElementFunction like in the following example:
SeedRandom["DistributionChart"];
data = RandomReal[NormalDistribution[], {100}];
DistributionChart[data,
ChartElementFunction ->
ChartElementData["SmoothDensity", "ColorScheme" -> "DeepSeaColors"]]

But the "ColorScheme"seems to get irgnored if I change "SmoothDensity" for "DensityQuantile"
I tried to change the colors using ChartStyle but I only got the following, unsatisfactory result.
DistributionChart[data, ChartStyle -> "DeepSeaColors",
ChartElementFunction -> ChartElementData["DensityQuantile"]]
