Interesting question... why do we always make level -1 through level 3 the same colors (for the most part)? If you have 6 - 9 levels would it be better to "lighten" -1 through 3 so that the highest level is not too dark? i.e. maybe our current shade for level 3 is now level 6 and we lighten up all the way down?
I assume we do it because -1 to 3 is "normal" and deviating from that might confuse us...
You should have seen the map for Kohima. 20 levels. Really hard to figure that one out, but I think we got there eventually.
Real-life mapmakers (and people who work with geographic info systems) spend a lot of time thinking about palettes, both gradient and banded (a given number of colors). How the palette affects the message of what's being displayed, etc. Fascinating stuff.
Over time, the green-to-brown-to-white progression has become pretty standard, I guess because it works. It's like the Times New Roman of palettes; won't dazzle anybody, but is just a solid, reliable, set.
Given the ETO location of Inor, and the prevalence of Green terrain types, it seemed fine, and not worth over-thinking.
Now, the DTO maps we've done for LFT, THOSE have a different palette
