Trackcolor The "Trackcolor" is the color of the background of the sliding bar on the right of your screen. You can choose from either the standard colors in the square "color" box or pick your own more custom colors from the web palette to the right of the Colors box. To use this palette, simply put your cursor over a color lightly to view it on top. When you find one you like, click on it and the number of the color will appear in the "Choose Bar Color" box. You can mix and match any color. This option is for the trackcolor. If you can see green on the track to the right of this page, this option will work for you.The other box is for the sliding bar color. After you pick your colors, click view and make sure you like them before going on, although you can change them at any time. Have fun and make them match your auctions, have red and green for Christmas, Orange and Black for Halloween or use your imagination!
