(each value corresponds to one color : 0 is red, 45 is a shade of orange and 55 is a shade of yellow).

Ranges from 0 to 360° in most applications.

Hue : the color type (such as red, blue, or yellow).

The HSB ( Hue, Saturation, Brightness) color model defines a color space in terms of three constituent components: Return Red.GetHashCode() ^ Green.GetHashCode() ^ Blue.GetHashCode() If(obj= null || GetType()!=obj.GetType()) return false Red = (value>255)? 255 : ((value /// Gets or sets red value. Public static bool operator !=(RGB item1, RGB item2) Public static bool operator =(RGB item1, RGB item2) / public static readonly RGB Empty = new RGB() Then, how can we display colors as numbers? the answer: color models. Colorimetry is used in chemistry, and in industries such as color printing, textile manufacturing, paint manufacturing and in the food industry.' ' Colorimetry is the science that describes colors in numbers, or provides a physical color match using a variety of measurement instruments. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra.'

Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. ' Color (or colour, see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, yellow, white, etc.

It will be a tutorial on how to create your own editors. Part 3: Will be about how to use those color controls at design-time.I will share a lot of my custom controls for this purpose. Part 2: Will be about dedicated controls, or how to select/define a color with custom components.Part 1: This one, will be an introduction into color spaces, and the most used ones.The proposed article content will be as follows:

That's why I publish this series of 3 articles. I've started looking for other formats, like CMYK, when I was learning how to add cool design-time support to my custom controls.īut, I quickly understood the utilities I was coding would be more than useful in other projects, like my SVG editor. It is largely sufficient for simple uses, like changing the background color of a component, but insufficient if we want to develop graphic tools (or something which implies conversion between color formats). Those two are encapsulated in the Color structure of the System.Drawing namespace. NET, there are only two color formats that can be used: the RGB color model and the HSB color model. Why an article on 'colors'? It's the same question I asked myself before writing this series.

The following example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. HtmlColor is not a valid HTML color name.
