vertical ruler color setting

 Thanks very much for implementing the 'gutterForeground' setting in build 2020. Allowing setting the colour of line numbers to other than a modified version of the 'foreground' setting is awesome.

Would it be possible to do the same for the vertical ruler colour setting?

In some uses having a vertical rule establishing the tab settings is very useful and for that case I would like to set a colour a shade or two away from the background so the readability of the text is maintained.

In some uses the ruler being brightly highlighted would be ideal.

If I was able to set the ruler colour then these different cases could be handled better than the current fixed setting allows.

Thanks for any time considering this and especially for any time implementing it if you choose to do so.
