I would find it useful too, I just don't have the figures and I don't know how to get them quickly. Besides, there are other sources for this type of data on the web, so feel free to send me a file with the exact color index, and I'll see to it to include it. No larger than 8192x4096 please.

Making a color index is even more difficult because I use transparency on the map, that distorts colors. It's not easy to produce an automatically generated map that is still readable, so my focus is on making the various information types distinguisheable, not as exact as possible.

And before this gets discussed all geospatial layers will use current day data, there is no such thing as WWII GIS files.

But thanks the point of this thread is to collect suggestions so I will put "exact color index" down under nice to have.
