Abstract
Color selection and display methods and devices in which colors can be displayed according to color harmony and color emotion and feedback obtained on color emotion and color harmony evoked by selected color and/or color combinations.
Claims32
A computer implemented method for selecting colors comprising:
- associating, in dependence on a mathematical equation derived from measuring psychophysical responses of a plurality of test subjects to a first plurality of test colors, a color score with each of a second plurality of colors that are numerically defined in a color library;
- displaying on a visual user interface a combination of at least three colors from the color library;
- displaying on the visual user interface a combined color score for said color combination;
- wherein the combined color score is calculated using a controller as follows:
- (a) calculating for each unique pair of the color combination that are adjacent to each other an adjacent pair color score using a first equation in dependence on the color score of each color in the adjacent pair;
- (b) calculating for each unique pair of the color combination that are non-adjacent to each other a non-adjacent pair color score using a second equation in dependence of the color score of each color in the non-adjacent pair;
- (c) wherein the combined color score =1/n·(Σadjacent pair color score(s)+Σnon-adjacent pair color score(s)), where n is the total number of unique adjacent and non-adjacent pairs in the color combination.

A method for organizing a color library comprising a plurality of colors, said method comprises the steps of:
- calculating, using a controller, a color emotion score for each color in the color library according to a mathematical equation derived from measuring psychophysical responses of a plurality of test subjects to a plurality of test colors;
- wherein the color emotion score comprises at least one of exciting-calming, warm-cool, light-dark, clean-dirty, happy-sad, fun-serious, or inviting-uninviting color emotion, wherein the color emotion score for warm-cool is calculated by the equation:
- Warm=0.02+0.12(C*ab)0.6 cos(hab−45°)−(1.5×10−8)(L*)3.9, where C*ab, hab and
- L* represent CIELAB chroma, hue angle and lightness, respectively;
- grouping the colors in the color library into N groups of colors according to the color emotion scores for the colors, where N is a positive integer;
- and
- displaying the colors from at least one group on a visual user interface in dependence on a user input.

A computer implemented color selection method, comprising:
- providing a color library comprising a plurality of colors;
- receiving user input identifying a desired color emotion threshold based on human psychophysical perception, wherein the color emotion threshold comprises a color emotion score in at least one of exciting-calming, warm-cool, light-dark, clean-dirty, happy-sad, fun-serious, or inviting-uninviting color emotion, wherein the color emotion score for warm-cool is calculated by the equation:
- Warm=0.02+0.12(C*ab)0.6 cos(hab−45°)−(1.5×10−8)(L*)3.9, where C*ab, hab and
- L* represent CIELAB chroma, hue angle and lightness, respectively;
- receiving user input identifying a desired color harmony threshold based on human psychophysical perception;
- filtering, using a controller without consideration of a user-chosen reference color, in dependence on a first mathematical model that models the first human psychophysical emotion, and on a color harmony mathematical model based on human psychophysical harmony, the plurality of colors in the color library to one or more colors that would achieve the desired color emotion threshold and the desired color harmony threshold;
- and
- displaying said one or more colors on a visual user interface.
