Colors can also be a burden, especially for -people with visual impairments. - -The goal of color management is to take full advantage of colors while -reducing the disadvantages of color use to a minimum. - -Color Schemes -============= - -Color Management is based around the concept of color schemes. -A color scheme defines colors for different elements in the -UI. The most important factor for the readability of a UI is the -contrast between foreground and background colors. Colors in a color -scheme are therefor grouped in pairs which define the foreground and -background color for a UI element. When composing a color scheme care -should be taken to use sufficiently contrasting colors for fore- and -background in the same group. When using colors in applications, care -should be taken never to mix foreground colors from one group with -background colors from another group: they do not necasserily have any -contrast at all which can lead to a completely unreadable UI. - -Color schemes are supported by Qt (see TQColorGroup) and can be -configured on a KDE wide basis from the Control Panel. The settings -are stored in the global KDE configuration file under the "General" -setting. The KApplication class takes care that the configured -settings are passed on to Qt. Application developers can just use the -values provided by TQColorGroup. - -There are three major color categories: - -General -======= -The colors in this group are used when no particular other group is -relevant. - -TQColorGroup...: ColorRole::Background, background() -KDE config key: background -Control Center: i18n("Window Background") -Description...: General background color -Example use...: Background of dialogs - -TQColorGroup...: ColorRole::Foreground, foreground() -KDE config key: foreground -Control Center: i18n("Window Text") -Description...: General foreground color -Example use...: Text in dialogs - -Text Areas -========== -The colors in this group are used where the user can type text. it is -also used for lists from which the user can choose. - -TQColorGroup...: ColorRole::Base, base() -KDE config key: windowBackground -Control Center: i18n("Standard background") -Description...: Background color for text areas. -Example use...: Background in a word-processor. - -TQColorGroup...: ColorRole::Text, text() -KDE config key: windowForeground -Control Center: i18n("Standard text") -Description...: Text color for text areas. -Example use...: Text in a word-processor. - -TQColorGroup...: ColorRole::Highlight, highlight() -KDE config key: selectBackground -Control Center: i18n("Select background") -Description...: Background color for selected text. -Example use...: In a selection list. - -TQColorGroup...: ColorRole::HighlightedText, highlightedText() -KDE config key: selectForeground -Control Center: i18n("Select text") -Description...: Text color for selected text. -Example use...: In a selection list. - -"Base" and "Text" should have high contrast as well as "Highlight" and -"HighlightedText". In addition, "Highlight"/"HighlightedText" and -"Base"/"Text" are supposed to be sufficiently different to get a clear -indication of what is selected and what is not. - -Buttons -======= -The colors used in this category are used for buttons in the broad -sense, including e.g.scrollbars, menubars and -popup-menus. - -TQColorGroup...: ColorRole::Button, button() -KDE config key: buttonBackground -Control Center: i18n("Button background") -Description...: Background color for buttons. -Example use...: Background color of the OK button in a messagebox. - -TQColorGroup...: ColorRole::ButtonText, buttonText() -KDE config key: buttonForeground -Control Center: i18n("Button text") -Description...: Color for text on buttons. -Example use...: Color of the OK text on a button in a messagebox. - - -In addition to the above colors a number of derived colors are -defined.They are all darker of lighter version of "Background". - -TQColorGroup...: ColorRole::Shadow, shadow() -Description...: Used for shadow effects.(Very dark) - -TQColorGroup...: ColorRold::BrightText, brightText() -Description...: Used for text on pushed pushbuttons - -TQColorGroup...: ColorRole::Light, light() -Description...: Lighter than "Button" - -TQColorGroup...: ColorRole::Midlight, midlight() -Description...: Between "Button" and "Light" - -TQColorGroup...: ColorRole::Dark, dark() -Description...: Darker than "Button" - -TQColorGroup...: ColorRole::Mid, mid() -Description...: Between "Button" and "Dark" - -Well Behaved Aplications -======================== - -Applications should never hardcode colors but always default to the -colors from the users color scheme. This ensures consistency among -applications on the desktop. It also ensures that all applications -are equally readable. - -An application may offer the user an option to change the color of -certain aspects of the application. It should be noted that an -application specific color setting can cause unexpected results when -the user changes its color scheme. The application specific color may -look ugly in combination with other color schemes or the resulting UI -may even become unreadable. Therefor applications specific colors -should be used with care. - - |
