Visual Guidelines
The feed icon should be displayed in its entirety on either a solid light or dark background (avoid mid-tone or strongly colored backgrounds). The feed icon should not be displayed in parts or with other elements superimposed on top of the icon.
The feed icon should be displayed at a size that is both large enough to render it legible to its intended users and compatible with the size of any related text elements.
The feed icon may be displayed using the colors black and white in contexts where color reproduction is not possible. The feed icon may be used with the colors of the icon inverted (e.g., white used instead of orange and vice versa), as long as there is adequate contrast between the background and foreground colors.
When used as an element in a user interface (e.g., as a toolbar button) the feed icon should be displayed in a manner consistent with related UI elements and any applicable user interface standards (e.g., for the underlying operating system and/or window system).
The feed icon should not be displayed in modified forms inconsistent with the above guidelines or in ways that visually compromise the icon. In particular, the icon should not be displayed
* in a different orientation (i.e., rotated or flipped relative to the standard orientation)
* with the rounded square element of the icon replaced by a circle, triangle, or any shape other than that used on the original background
* with the corners of the rounded square element of the icon made sharp rather than rounded.
Note that the above guidelines regarding size and color are not intended to restrict the ways in which the feed icon might be represented by assistive technologies designed for use by people with impaired vision. (Such technologies include software to magnify the contents of the screen and/or change screen colors, contrast, and brightness; alternative stylesheets for web sites; and the like.)
Note also that these guidelines are not intended to discourage other uses of the feed icon that conform to the overall spirit of these guidelines. Such cases include using different colors for the icon where appropriate (e.g., in matching a site theme) or using the icon in combination with other icons of a compatible style and nature (e.g., to identify the type of feed being offered). However in the interests of providing a consistent experience for users we suggest that providers of feed readers and related goods and services make minimum use of such alternative representations of the icon.
