Create new style into Joomla template

Working site: [login to view URL] Base combination to use as start, style n.3. You should create a new style into the selected template of a joomla running installation. In the screen we have fundamentally two main parts of color, top and lower one. Top side will have as basic color #585858, gradient used in the top part of the template will be respected with new color. Lower side (left and right column) will have as basic color #0d0d0d. Red color used for example in the first world of every highlights of the must be the following #ffff33, all red color into the template should be changed into yellow color so it should be used also for color the selected radiobutton on mouseover of the left menu. All green and red in the style three (radio button, button, text) should be revert into #ffff33. It would be important to have a document on the code and file & folder change applied to create the new style so it would be easy to re-create them in case of reinstallation.
