 <p>Two styles of icon are used in GNOME 3: full-color and symbolic icons.</p>
 
-<p>Full-color icons are colorful and detailed, and are optimized for larger sizes. They are defined as 
128x128px SVGs, and can be scaled up in multiples of 128 (such as 256✕256 and 512✕512). They should not be 
enlarged to other sizes, as this will result in them no longer being sharp. The design of full-color icons 
also allows them to be rendered sharp at 64x64px and 32x32px, but is not advised to go lower.</p>

-<p>Symbolic icons are simple and monochrome, and are designed to work well at smaller sizes. They are 
defined as 16✕16px SVGs, and can be scaled to multiples of 16 (such as 32✕32, 64✕64, 128✕128). Symbolic icons 
generally have a neutral color, although their color can be changed programatically.</p>
