It is interesting but I think Razed team can change those colors.
In my opinion, Green for increase, and Red for Decrease. It is popularly used by exchanges and using Green for decrease is quite abnormal and sometimes can confuse Razed.com users. It won't be a big change and if Razed.com think it is reasonable for color change, they get my support.
Other community members can share their thinking about current colors and whether they want changes or not.
team razed must have had their reasons for using this color scheme. i think they're making it green = decreasing, but players can still play because it all depends on their luck.. and orange = increasing, but players should still be cautious and gamble responsibly. that's just my personal opinion. but team razed also includes up and down symbols, so players shouldn't be confused by this.
