Yes there are a large number of tools that will help you change the color. Look under the Adjustments menu, or in the Effects > Color menu.
Try Curves or Curves+ (if you have it installed), Color Balance+, there are many more.
You might also try the Recolor tool . Set the secondary color to black, set the primary color to your new color, increase the size of the brush width a bit & draw over your image. Increasing the tolerance in the toolbar will help clean up any stray pixels on the edges.
