I don't think you can do it.
how do i get rid of the annoying last move yellow and blue colors
Thanks for the reply,but I think there should be a way to remove them.I wonder if they are just a distraction to me?I mean ,if you dont know what you or your opponents last move was, you are not gonna win many games

Yes you can by going to "Account" - "Online Setting"- untick the box next to the "move highlights" then click on " save setting"
Thanks, I think i tried that and it did not work,will try again.Maybe you have to log out and back in for it to work.Again thanks
I did all that and it is still doing it, i may have done that a long time ago, cause I think the colors just started showing again tonight.Maybe its a site problem

I don't think you have to logout here in order to activate changes in your settings. What OS, browser, and hardware are you using? See if my blog has any useful suggestions (such as switching browsers when you can't do something in your regular browser) If not you can contact the staff directly by clicking on Help & Support at the bottom of the page
