If you want to go back to the old ET color palette, go to the Edit Options section of your account at http://www.elitetrader.com/vb/member.php?s=&action=editoptions You'll see an option to change the style of the forum at the bottom. You want to select "Classic" and then click the "Submit Modifications" button. At this time, this style change will apply to the forums only, not the homepage or other areas.
The colors are totally washed out, hard on the eyes. Why not make the new blue color an option instead of the old classic colors? The home page is still blue even when I change to classic colors.
