graph hbar specify color of blabel

[Marc Kaulisch]

I wonder whether it is possible to manipulate the color of a blabel for a specific bar. My use case is that I like to use white color blabel but with some bar colors it is not appropriate and I like to switch to another color for one or two barlabels.
I know that this is manually possible with the Graph recorder but I like to integrate the manipulation directly into the graph hbar code.

My code as follows. I deselected a section in which I use two packages from Ben Jann: 1) colorpalette (Jann, B. (2018). Color palettes for Stata graphics. The Stata Journal 18(4): 765-785.) from https://github.com/benjann/palettes/
2) grstyle ( Jann, B. (2018a). Customizing Stata graphs made easy (part 1). The Stata Journal 18(3): 491-502. Jann, B. (2018b). Customizing Stata graphs made easy (part 2). The Stata Journal 18(4): 786–802.) from https://github.com/benjann/grstyle/ - Both packages are available from SSC as well. If available and of interest you can reselect this part of the script.

At the moment my solution is to use a different color that works with black as blabel color.
So RGB color "176 141 58" works well for me.

Nonetheless, for other applications it would be great to know if a color of a specific blabel can be manipulated with a command.
