Abstract: A method for controlling color styles in a graphics application program includes the steps of selecting a plurality of color styles and grouping the color styles into a harmony. The method further includes the step of displaying a color model graphical user interface representative of each color style in the harmony. The method further includes the steps of creating a rule in program instructions for the graphics application program to constrain at least one color component of the color model graphical user interface, selecting a base color style within the color model graphical user interface for editing, and invoking the rule so the computer executes instructions to constrain the color component. The method further includes the steps of modifying a color component of the base color style with the graphical user interface while in the constrained state, and proportionately modifying the corresponding color component of the remaining color styles in the color model graphical user interface.

Abstract: A method includes the steps of: providing a computer readable non-transitory storage medium including a computer readable code configured to run on a computer and to perform a process to view an assignment of a style to an object of a computer drawing; selecting the style for view; choosing by computer a sample object, the sample object configured to visually demonstrate one or more visual properties of the style; applying by computer the style to the sample object; rendering by computer the sample object to a bit mapped image suitable for display on a computer display; and displaying by computer the pixelated image on the computer display. A system to perform the method is also described. A method to assign a child style to an object, where the child style includes one or more properties inherited from a parent style is also described.
