Editor: Users with sensitive eyes might prefer to tone down the display because it hurts their eyes. Apple provides keyboard controls to control backlighting. Screen Shades lets you tint the entire screen.
When you launch Screen Shades, you see the Screen Shades Control Panel. This Control Panel lets you turn the effect on/off, select the desired tint (gray, blue, yellow, pink, and My Tint [a custom tint color]) and set the tint darkness.
Click the "My Tint" square if you prefer to choose your own tint color. The color window will be displayed. Select the desired color using any of the methods (color wheel, crayons, Sliders, etc.) and click on the "OK" button. The color selected will be displayed in the "My Tint" square. Select "My Tint" in the drop-down Tint Color menu to use this color.
You may drag the Control Panel out of the way and minimize the window if you wish (click on the yellow dot at the upper left corner). The effect will continue with the Control Panel minimized as long as you do not minimize it using the File / Hide Screen Shades menu item.
