+% Color configuration for the bidipresentation class.
+%
+%=======================================================================================================================
+
+%=======================================================================================================================
+% Standard colors.
+%
+% For every of the colors described in the "Defined colors for emphasis and highlighting elements" section of the
+% documentation, there is one default value which is defined here. Further default colors are for background, panel and
+% navigation elements.
+%
+% Note that this file is loaded _only_ if bidipresentation's color management is active.
+%
+% Redefine colors for individual taste. Please remember, however, that a document transferred into another configuration
+% where a different bidiprescolors.cfg is present, will look different on compilation. So for a `stable' color configuration,
+% it might be better to put the respective \definebidiprescolor commands into the preamble of the document or into a style
+% file.

+% calculated enhanced variant might not be to everybody's taste. The following example (if uncommented) will define

+% automatically calculated ones. Note that background and panels are not affected by dimming and enhancing.
