In French-made French VFR charts the shape and color of a built-up area defines the minimum altitude AGL: - Yellow circle: 1,700 ft AGL. - Yellow area (e.g. Sélestat): 3,300 ft AGL. - Orange area (e.g. Colmar): 5,000 ft AGL. I can't find this information in the Skydemon VFR charts for France. Is there a way to add that information? Thank you

But to know which cities are which color one has to look at the 1/500 000 ICAO chart, the color key is in the legend of that chart. May be it is possible to ask french SIA, the editor of the chart if they have a table with the cities and corresponding color. Chart legend
