        Secondary windows background
        
+
        Secondary windows (such as messages, questions, the “Theme Selection window” the “Encoding Selection window”, etc.) originally use the same background color as the “Main window”.
        
+
        It is now possible to use a different background color for these windows, to get better visual result.
        
+
        There are two way to do that:

        Messages Border     #a3b367 #F5DBDE
        
+
        In this case, this color will be used as the Secondary Windows background color.
        
+
        Although one can use any color here, it is recommended to follow these guidelines for best visual result:
        
+
          
+
        1. The color should be 1-20% lighter or darker than the “Stations Background” color setting of the theme.
          
+
          
+One can use this page (or a similar one) to insert the base color and adjust the “L” component as needed.
          
+
          
+A terminal alternative is pastel, which can be used like so:
          2. 
+
        
+
        pastel color '#fbf1f2'              # show color info
+pastel lighten .1 '#fbf1f2'         # color lightened by 10%
+pastel darken .1 '#fbf1f2'          # color darkened by 10%
        
+
          
+
        1. If the “Stations Background” color is dark, create a lighter version of it; if it’s light, create a darker version of it.
          
+
          
+This is just a recomenration, though; just get a color that combines well with existing ones (border foreground, stations foreground and active station).
          2. 
+
        
+
        This information is actually relevant to creating a new PyRadio theme, but it’s very important in order to understand how the calculated background color works.
        
+
        Calculated secondary windows color
        
+
        PyRadio will use the same background color for all windows by default, provided that the theme used does not define a “Messages Border” background color.
        
+
        In order to use a “Messages Border” background color different than the “Stations background” color, when “Messages Border” background color is not defined in the selected theme, a config option is available; “Calculated color”.
        
+
        This config option takes a value that’s between 0 and 0.2.
        
+
        If it is 0, no color change will occur.
        
+
        Otherwise, the value acts as a percentage (a factor), which indicates how much the luminance of the “Stations background” color will change to produce the new background color.
        
+
        This is how this works: PyRadio will calculate the “Stations background” color perceived brightness, which will indicate whether the color is dark or light. Then depending on that, will add or subtract factor percent from its luminance value.
        
+
        Finally, a check will be made to see if this color is close to “Messages Border” foreground color, and re-adjusted as possible.
        
+
        Note: When a calculated background color is used, pressing “~” (tilde) will toggle it on and off. This setting will be valid until PyRadio terminates, or a new theme is loaded.
