# Making a black bar in BarChart when using GlassRectangle [closed]

I use the command:

BarChart[{1, 2, 3}, ChartLegends -> {"a", "b", "c"},
ChartStyle -> {Blue, Red, Black}, ChartLayout -> "Stacked",
ChartElementFunction -> "GlassRectangle"]


But the result is that the black bin comes out gray:

Using RGBColor or Lighter/Darker did not help. The "GlassRectangle" look is very appealing but I do need it to be black or at least much darker. Any ideas? Many thanks, Dan

• I get a black bar with Mathematica 10.0.2 under Win 7. – Karsten 7. Mar 26 '15 at 17:02
• Works as as expected with 10.0.2.0 for Mac OS X x86 (64-bit) (December 4, 2014). – user9660 Mar 26 '15 at 17:59
