Icons are pictorial representations of functions and objects, important not only for aesthetic reasons as part of the visual identity of a program, but also for utilitarian reasons as shorthand for conveying meaning that users perceive almost instantaneously. Well-designed icons improve the visual communication and strongly impact users' overall impression of visual design. Last but not least, icons are space-saving and improve usability by making programs, objects, and actions easier to identify, learn. Icon use should be consistent throughout the interface.
== Guidelines ==
* Design icons with a small number of metaphors [1].
** Apply metaphors only once (e.g. do not use a brush twice for different options).
** Rethink conventionally used metaphors (e.g. the clipboard icon of paste).
** Antiquated metaphors might work well (e.g. a floppy is not necessarily outdated to represent save).
** Adjust the degree of abstractness according to familiarity of the metaphor.
** Use arrows only if they can easily be related to spatial features such as ''Previous/Next'' in a sequence or ''Up/Down'' in a hierarchy. Avoid using arrows metaphorically (such as for ''Reply/Forward'' or ''Undo/Redo'').
** Attempt to use metaphors that are independent of language and culture.
** Make icons simple.
* If an icon has important details at larger sizes, rather than simply scaling it down, create unique versions of the icon at smaller sizes. Critical details may become unrecognizable when scaled down.
* Avoid using text in icon designs; it may not scale well to smaller sizes.
* Icons of a similar type share a consistent visual language (mimetypes, folders, devices, etc.).
* Follow the guidelines for presenting [[KDE_Visual_Design_Group/HIG/IconsAndText|icons with text]]
* Test your icon set on strength of association, discriminatory power, conspicuousness, and, if applicable, on accessibility.
=== Monochrome Icons ===
* Used for application toolbar and button actions, menus, sidebars and status and notifications. Also may be 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.
* Breeze icons use primarily color #1 and #2 but also use other colors to indicate a different state.
:# [[File:Icon_Grey1.png|40x40px]] [[KDE_Visual_Design_Group/HIG/Color|Icon Grey]]  - Color used for icons in a normal state and non destructive actions e.g.: back, forward, ok, home.
:#[[File:Icon_Red.png|40x40px]] [[KDE_Visual_Design_Group/HIG/Color|Icon Red]] - Color used for icons in a normal state and for destructive actions e.g.: close, delete, remove, stop. Also used in addition with color #1.
:#[[File:Icon_Orange.png|40x40px]] [[KDE_Visual_Design_Group/HIG/Color|Icon Orange]] - Color used in addition to color #1. Used to distinguish icons that involve "user input", also used as the color for the "busy" state in IM software.
:#[[File:Icon_Blue.png|40x40px]] [[KDE_Visual_Design_Group/HIG/Color|Icon Blue]] - Color used in addition to color #1. Used to distinguish icons that involve the action "select" or "insert".
:#[[File:Icon_Yellow.png|40x40px]] [[KDE_Visual_Design_Group/HIG/Color|Icon Yellow]] - Color used in addition to color #1. Used to distinguish icons that involve a "warning", also used as the color for the "away" state in IM software.
:#[[File:Icon_Green.png|40x40px]] [[KDE_Visual_Design_Group/HIG/Color|Icon Green]] - Color used in addition to color #1. Used to distinguish icons that involve "connected", "secure" or "successful" actions.
=== Colorful icons ===
[[File:Sample color icons.png]]
* Use colorful icons for applications, folders, mimetypes and devices.
* For Breeze icons, use colors from the [[KDE_Visual_Design_Group/HIG/Color|full Breeze color palette]] as a starting point.
* Breeze icons use smooth linear gradients (bottom to top/dark to light); they are not flat.
* Application icons should be unique and easily recognizable.
* When creating an system icon theme, respect trademarks by avoiding significant alterations to application icons.
* Use icons available from the system icon theme whenever possible. Avoid using custom icons.
* Follow the [[KDE_Visual_Design_Group/HIG/IconTheme|Icon theme usage guidelines]].
* For standard actions (back forward, open, save, refresh, etc.) use an icon from the platform-provided set. The KDE Platform 4.x uses the [http://websvn.kde.org/trunk/kdesupport/oxygen-icons/ Oxygen icon set]. The KDE Plasma 5.x desktop and applications use the Breeze icon set.
* If you would like to request help designing icons unique to your application, you can ask for help on the [http://forum.kde.org/viewforum.php?f=285 KDE Visual Design Group Forum].
