Windows allows you to change the color of window borders and the taskbar. You can choose from a variety of preset colors and also enable the Transparency feature, which gives an attractive glowing effect to these desktop elements.
Right-click the desktop, and choose Personalize.
Click Color.
Click a color scheme to preview it.
Click Save Changes.
You can adjust the depth of the color by using the Color Intensity slider. More intense color depth makes the color palette darker.
