Parallel Coordinates Axis Text Shadow

[salo]

Hi,
I have changed the color background of a Parallel Coordinates chart to black.
I see that the text in the vertical axis has a white shadow that looks like it is impossible to change.

Since with a black background it is impossible to read, how can I change the shadow color?

Thanks
Ivan
