Dimension Inherit

I'm attempting to change the dimension lines and text color.  The settings were set to Inherit color and I can't change this (not sure what I have missed).  The goal is to use ByLevel for the dimension color.  What I have attempted is select ByLevel for the color under Dimensions Lines and Text.  Since that did not work I also tried by unchecking Color for each.  What I get for either scenario is the same color no matter the level I'm on.  Please advise an inexperienced MicroStation user.

Thank you,
