Color correction with a long chain of keyers and math operators, even in the hands of experienced artists, often induces artifacts such as muddy colors or malformed edges. Inspired by tools which display a 3D color histogram [COL 2007], and Flame's Color Wrapper [WRA 2019], we embarked on building a user-friendly 3D color space sculpting toolset which ...

Color Classification in a Multidimensional Color Space
2007 IEEE International Symposium on Signal Processing and Information Technology, 2007In this paper we proposed a color classification method which consists firstly to select through a multi-stages process the most discriminating color components for a given image among a set of conventional color spaces. To compute the most discriminating components we used the PCA technique on the lightness components, next on the mono-chromatic ...

Color Spaces and Human Color Perception
1994This paper is concerned about the definition and features of color spaces in general, about the differences between geometrical and perceptual color spaces and about one possible way to create a colorimetrie system, which is more based on human color perception than color spaces commonly used in computer graphics.

Blends and combinations that occur in the world of color are of a great variety. The combinations vary from barely perceptible changes to the most intense contrasts. The vast world of color is explored in search of criteria for its organization, its diversity and complexity being evidenced, identifying three strategic fields for performing work: the ...

Hue is a sensory initiator of the experience of space. In the visual field bright hues arrest the eye, localizing as they isolate themselves from their surroundings. The aggressiveness or visual insistence of red is a spatial phenomenon, as is the radiating effect of a yellow, or the recessive quality of a light, desaturated blue.
