The Highlight Selected Colour option is used to identify colour swatch used in a drawing. For example, if you have unnamed colours in your palette and want to know if a particular colour was used on the current model or drawing, you can select the colour and use the Highlight Selected Colour option. Harmony will dim all the colours in the drawing except the selected one, so it stands out and can be identified. You can rename it accordingly.
