Abstract
Abstract After an initial starting single color may or may not be provided, the user may indicate a global sensation, such as morning, so that all colors inputted thereafter will be modified by the global sensation, or input a basic color, such as blue. In either case, menu driven user input information may include any number of human sensations relating to color for modifying the previously compounded color. In each case, the newly compounded color is displayed in a color display area on the screen. Thus formed, new colors may be named and stored to be retrieved at a later date. The menus on the display screen may be grouped according to basic decisions, basic colors, and compounding modifications according to human sensations, which latter may be subgrouped according to specific types of sensations such as mood, feeling, temperature, and the like.

Claim 2
Dependent Claim
223 words
Color display apparatus, comprising: a color display screen; input means for inputting user information; computer means for receiving the user information from said input means, for displaying information, including colors, on said screen, and for processing data; means for storing a plurality of separate different rules for compounding a fixed number of primary colors, with said rules including separate basic color rules fixing the proportion of said primary colors for each of a corresponding plurality of basic compound colors, and separate modifying rules for modifying, each in a fixed manner, the proportions of the primary colors as stated in the basic rules for producing modified compounded colors; means for providing a first menu of basic compounded colors; means responsive to input information from said input means for selecting a basic color from said first menu to retrieve the corresponding basic color rule from said means for storing and to display the color corresponding to the retrieved basic color rule on said screen; means providing a second menu of modifiers for said basic colors; and means responsive to input information from said input means for selecting a modifier from said second menu to retrieve the corresponding modifying rule from said means for storing, modifying said retrieved basic color rule according to said retrieved modifying rule and displaying the resulting compounded color on said screen.
Claim 3
Dependent Claim
22 words
The display apparatus according to claim 1, wherein said screen includes a fixed color display area for receiving the displayed compounded color.
Claim 4
Dependent Claim
46 words
The display apparatus according to claim 2, wherein said screen includes a fixed area for displaying said first menu and a separate fixed menu display area for displaying said second menu, each of said menus being displayed in an area separate from said color display area.
Claim 5
Dependent Claim
53 words
The display apparatus according to claim 3, wherein said computer means includes computer aided design software and hardware for creating and displaying drawings on said screen, and said computer means further including menu driven user input means for transferring said compounded color to a selected portion of a drawing appearing on said screen.
Claim 6
Dependent Claim
23 words
The display apparatus according to claim 1, wherein said means for selecting a modifier further modifies a basic color rule as previously modified.
Claim 7
Dependent Claim
77 words
The display apparatus according to claim 1, further including menu driven user input means for selectively making with a unique name any compounded color as a new basic color, storing compounding rule information for exactly duplicating said new basic color at a storage address corresponding to said name, and thereafter displaying said new basic color in response to user input of said name so that it may be directly accessed during any subsequent usage by the user.
Claim 8
Dependent Claim
37 words
The display apparatus according to claim 1, wherein said color modifying rules are divided into rule groupings having menu indicia for correspondingly addressing said modifying rules, with the indicia being grouped according to human senses and emotions.
Claim 9
Dependent Claim
25 words
The display apparatus according to claim 7, wherein said indicia include indicia groupings of quantity of light, touch, mood, clarity, physical appearance, and scenic imaging.
Claim 10
Dependent Claim
18 words
The display apparatus according to claim 1, wherein said means for storing includes a table of said rules.
Claim 11
Dependent Claim
45 words
The display apparatus according to claim 1, wherein there are three of said primary colors, and said rules each specify output proportions of the three primary colors that are fixedly proportional to the input proportions of said three primary colors of the current compounded color.
Claim 12
Dependent Claim
45 words
The display apparatus according to claim 1, wherein there are four of said primary colors, and said rules each specify output proportions of the four primary colors that are fixedly proportional to the input proportions of said four primary colors of the current compounded color.
