Give them outlines, pic of bad UI control embedded
Dear GC dev team:
Please consider tweaking the UI by giving UI elements contrastive outlines or something to help make them visible, even when they appear over background that is of similar color/brightness. This screenshot of the > diplomacy control to cycle to the next civ for diplomacy is a good example; it is very difficult to see the > control due to it being white over the brightness of the background image.
Thanks for considering this!
