Aged & Monochrome maps
If you're looking for a really old looking map, select the "Aged" tone for your map. If you want the map to be much less colourful, select "Monochrome".
Move the sliders to compare the Original, Aged and Monochrome tones. See lots more examples.
Here is a John Speed map, in the Original colour tone and Monochrome.
Here's an Original/Aged example of the Anglo Saxon Heptarchy.
And one more of the Roman Empire.
