Color Confusion

I set a color for the label “-Editor Changes Implemented” to a dark blue, but as shown by the arrow below, it comes out as a purple.

The other colors (transferred from my Windows projects) seem to be okay.

What am I missing?

By default, labels used in background areas are faded out a little, to stop them from being too full-on. If you really want them full-bright, go to the “Appearances” pane of the Preferences and in the “General Interface” section turn up “Opacity of label colours when used in backgrounds” to the highest setting.

Yes, that worked. I can now get exactly the color I want.
