Hi Dave, Thanks for the reply.
I did some test in another clean environment and found that it is working. ( IT seems that the client Clarity installation is with some problem - checking to see if this is the problem ).
The colors must be in the Color Palette.
If you use Consistent Colors in the Chart ( a pie chart for example ), you can choose the color you want by giving the index number of Color Palette. So if you want your value to use the red 14 color, the black 4 color, the white 5 color and the DarkOrange 6 color , you would use as index 14, 4, 5 and 6 for the color number.
If you use the default color palette, then you must use the color as you explained in your other posts.
I will run more tests and let you know the results.
