Revit is still somewhat short on naming colours. All users get is some RGB values - if their props display width is sufficient. I propose to enhance the global parameters introduced some years back to allow for parameters like 'CorpCol1', 'Highight', 'New', 'Demolish', 'Existing' or 'WasteWater' etc., to have an RGB value that you can use whereever such values are required by Revit. That way you could setup a specific hue for all annotations which you would currently have to setup for each annotation individually. One municipality may require demolished things to be displayed in yellow another wants it in orange.
