Netbeans properties window - change font color for non-editable properties

Hello everyone,
I want to customize the look of ReadOnly properties in Properties window.
Reading this:
http://bits.netbeans.org/8.1/javadoc/org-openide-explorer/org/openide/explorer/doc-files/propertyViewCustomization.html
I've found that I can remove the "three dots" button for a custom viewer.

Is there any simple way to change the font color of non-editable properties
from light-grey to just regular black?

This tutorial:
https://platform.netbeans.org/tutorials/nbm-property-editors.html
explains how to install a custom editor, but it looks like too much and I'd
need to replace all the editors for all types.

Thanks,
Dima
