class HighLine::ColorScheme

ColorScheme objects encapsulate a named set of colors to be used in the {HighLine.color} method call. For example, by applying a ColorScheme that has a :warning color then the following could be used:

color("This is a warning", :warning)

A ColorScheme contains named sets of HighLine color constants.

@example Instantiating a color scheme, applying it to HighLine,

and using it:
ft = HighLine::ColorScheme.new do |cs|
       cs[:headline]        = [ :bold, :yellow, :on_black ]
       cs[:horizontal_line] = [ :bold, :white ]
       cs[:even_row]        = [ :green ]
       cs[:odd_row]         = [ :magenta ]
     end

HighLine.color_scheme = ft
say("<%= color('Headline', :headline) %>")
say("<%= color('-'*20, :horizontal_line) %>")
i = true
("A".."D").each do |row|
   if i then
     say("<%= color('#{row}', :even_row ) %>")
   else
     say("<%= color('#{row}', :odd_row) %>")
   end
   i = !i
end
