ew: 

Any icons or graphics displayed by your application are designed to be distinguishable on low- (640x480), medium- (800x600), and high- (mega-pixel) resolution displays. Alternatively, your application provides different sized visuals for low-, medium-, and high-resolution displays. 

Desktop system configurations are including more high-resolution monitors. The user must be able to discern any visuals used by your application on these type of monitors. The embedded base, however, still contains many standard VGA monitors. Your application's visuals must display well on these systems and should not appear overly large. 

Recommended 

ex: 

Any icons or graphics displayed by your application are designed to display well on black-and-white and gray-scale monitors. These visuals also display well on low-color (16) systems. 

Recommended 

ey: 

Icons should be used to represent only objects and applications. 

Icons provide a visual representation for objects and facilitate direct manipulation. If icons are used for other purposes (for example, as illustrations) where the user can't drag them, select them, and so on, it creates a confusing inconsistency. 

Recommended 

ez: 

Icons should use only the palette of 22 colors. 

The Common Desktop Environment icon palette was chosen to maximize attractiveness and readability without using an unnecessary number of colors. Use of additional colors may cause undesirable color shifting on the display. 

Recommended 

fa: 

Icons should be designed for international use. 

Don't use text, symbols, humor, animals, and other items that may be interpreted differently in other cultures.  

Recommended 

fb: 

16x16 and 32x32 icons are left-aligned; any empty bits are on the right side of the bounding box. 

Recommended 

fc: 

48x48 icons are centered in the bounding box.
