Customizing meter colors in Ardour 4

I’m attempting to change my meter color and have added aliases in the colors file to link to the ‘meter color x’ properties. I’ve read in the manual that Peak/RMS meters are able to be themed. My indicator colors still show the default value. Are meter’s not able to change color values?

Here you can read about meter colors:

Some kind of meter’s mode can’t be changed via Edit>Preferences>Theme. And have some reasons (as I know there are some world standardized colors, which better to leave unaltered)
