Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

I don't know about you, but I struggled now for many years with the limited number of colors available in the Colors class, trying to get matching colors with ColorPickers and understanding the various color models. To simplify my life, I wrote few small methods which allow me to change any color towards white and black and another one to mix colors. With this, I get nicely matching colors, a bit like gradients as in GradientBrush. Then I had the bad idea to write a CodeProject article. To explain how my methods work, I had no choice but to investigate in detail what is going on. So the biggest part of this article is about colors, color models, hue, brightness and stuff, but in easy terms a software developer can understand without a math of physics degree.

Since I've been working in WPF a lot, it's jumped out at me how many features are conspicuously missing. The feature I'll talk about today is color picking. I'll start with the final dialog box, since I'll be referring to it later:. Computer color is a three-dimensional space, not least because there are three colors of filters in your monitor. The simpler color space is the colors of those filters—red, green, and blue—but it's also the hardest to work with. For normal use, we typically use a different three-dimensional space, of hue, saturation, and value. Hue is your position on the rainbow, so values of hue go through red-orange-yellow-green-blue-violet. Saturation is the "whiteness" of your color, and value is the "blackness. I followed Gimp's example, with saturation and value as the 2D selection, and hue as the 1D.

On the left and right end, there is each time a red. Implements a set of predefined colors. I discovered it when I had to parametrize Validation. I made few more methods I needed for writing this article, which might be useful too. Oct 27th, , AM 2. I have learnt that trick from him "parametrized templates" sounds more precise in my opinion.
