For a given pair of colors (i) and (j) of the same brightness, an observer generates in a visual colorimeter a third color (i,j) such that he perceives all three colors to be equally bright and the three differences between them to be of equal size.

Upgrading color-difference formulas
Journal of the Optical Society of America A, 2010We propose a method to improve the prediction performance of existing color-difference formulas with additional visual data. The formula is treated as the mean function of a Gaussian process, which is trained with experimentally determined color-discrimination data.

Color Demosaicing Using Variance of Color Differences
IEEE Transactions on Image Processing, 2006This paper presents an adaptive demosaicing algorithm. Missing green samples are first estimated based on the variances of the color differences along different edge directions. The missing red and blue components are then estimated based on the interpolated green plane. This algorithm can effectively preserve the details in texture regions and, at the

A new visual colorimeter has been designed and built to be used primarily for matching color differences. The colorimeter provides seven visual fields, arranged in a cluster of seven regular hexagons, one in the center and six adjacent to it. Both eyes of the observer see each field uniformly filled with light.

Image color-difference evaluation based on color-difference formula
2011 4th International Congress on Image and Signal Processing, 2011To study the relationship between calculated mean color-difference and visual perception of color digital images, a visual assessment experiment was designed and carried out. Based on the experimental results and color-difference formula, the performance of CIELAB, CIEDE2000 and CMC color-difference formula on evaluating image color-difference were ...

Color Matching and Color-Difference Matching
Journal of the Optical Society of America, 1972The precision of color matching is commonly described by color-matching ellipses, and the precision of matching color differences can be described by color-difference-matching ellipses. Recently obtained sets of color-matching ellipses and color-difference-matching ellipses have been compared and some important correlations are indicated.

Color difference predicted by color component differences
Color Research & Application, 2002AbstractA relationship between assessed color differences and assessed components of colors is presented. The perceptual difference between colors j and k is converted to a lightness difference of two Munsell grays, VA and VB, and djk = |VA − VB|. Scaled values of principal hue components of a color ξα(H|V/C), α = R, Y, G, and B, are read from charts ...

Large color differences among achromatic colors
Annual Meeting Optical Society of America, 1988Small color differences between simple achromatic stimuli have been understood for more than a century: extensive detection and discrimination data, including the Weber fraction, coexists with successful theories based on signal detection. Larger color differences and complex stimuli, which are more important in engineering applications, are less well ...

It is a common philosophical question as to whether your blue is the same as my blue. The two-tone striped dress shown in Figure 1, which attracted a lot of attention on the Internet, gave us a clear answer: "No." Some people see the dress as blue and black, whereas others insist it's white and gold. So your blue can be my white.

Color difference evaluation for wide-color-gamut displays
Journal of the Optical Society of America A, 2020With the emerging demand for wide-color-gamut displays, an issue has been raised in which the commonly used color difference formulae or uniform color spaces that were derived based on the data produced in the relatively smaller color gamut could be unreliable for predicting color differences in the highly saturated color regions.
