[ECS] The colour of Bauxite Transport Tycoon Forums

2011-12-1 George wrote: My suggestion for bauxite. Well, I´d say it´s more reddish, and more light. But that depends, deposits usually have their own colour tone. And keep in mind that almost all pictures are displayed with a tint, especially on the net. IMO, we should avoid to try to model a colour too "realistically", especially when there´s more
