Some features include: Support for a wide range of color spaces. CSS. RGB spaces tend to have a smaller gamut than some of the CIE color spaces. This is a simple example of a CIE Lab to CIE XYZ conversion. An HSV is another type of color space in which H stands for Hue, S stands for Saturation and V stands for Value.. A Hue represents color. Color.rgb - The color represented as a namedtuple of RGB from 0 to 255, e.g. Actually, in computer vision, we sometimes want to separate color components from intensity for various reasons, such as robustness to lighting changes, or … HSV, unlike RGB, separates the image intensity (lima), from the color information (chroma). In fact, the hue has a ra­dial or­ga­ni­za­tion, col­ors of each hue are arranged in a ra­dial slice. - ruozhichen/rgb2Lab-rgb2hsl. I recently wrote a post on RGB/HSL Conversions in Python and as a follow-up I decided to put together a simple Tkinter application which enables users to display a colour by selecting any combination of hue, saturation and lightness.
