The original my-modus-operandi-fg-blend color made every foreground face in modus-operandi look too
similar. While my-modus-vivendi-bg-blend previously had the same value as my-modus-operandi-fg-blend, it doesn't need to be updated since it still results in nice background colors and distinguishing them from each other is easier than foreground colors.
