    Monochrome Icons

    • Used for application toolbar actions, menus, and status and notifications. Also used for small (16x16) devices and places icons (folders, usb drives, etc.)
    • Rely on a distinct shapes instead of fine details to distinguish between them.
    • Color can be used for distinction (change of state, destructive actions, etc.).

    Application icons

    • Unique and easily recognizable
    • Respect trademarks by avoiding significant alterations to other application icons

    Other icons

    • Icons of a similar type use a consistent visual language (mimetypes, folders, devices, etc.)


    • Avoid using text in icon designs; it may not scale well to smaller sizes
