At least on my TFT screen some colors are hardly to recognise on the grey background:
yellow and light green. The grrey statistics (meal, gold ore) are absolutely invisible.
This mainly applies to the graphs which are only 1 pixel wide lines, to some extend also the number in top right corner.
Would be nice to change to darker colors with more contrast to background and probably bold lines for the graph.
Probably can be done by editing a configuration file?
Great Game - THANKS, Ingo
