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:

enter image description here

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

    $\begingroup$ I'm voting to close this question as off-topic because the problem can't be reproduced by others and the OP doesn't provide the version of OS and Mathematica used. $\endgroup$ – Karsten 7. Jul 24 '15 at 19:27

On my computer Windows 7, Mathematica 9, your code renders a perfectly black bar! To understand if problem may be OS or Mathematica version related, please specify OS and Mathematica version.

Result of your code on my computer
