The demos are very simple console apps that perform RGB conversions to and from HLS and HSB color equivalents. There are two demos attached to this article:

If you are one of those folks, please feel free to leave a comment. But naturally, there are those who disagree. The jog to the right that the HLS model takes seems to me to produce richer shades. I like the HLS model for doing percentage color adjustments, because I feel that the HSB model tends to de-saturate colors and move too quickly in the direction of dark gray. Which is the Correct Model?Įither color model will give good results it really boils down to personal preference. This time, the color space cursor will move straight down, without the jog to the right:Īs you can see, there are differences in the colors that result in some cases where B (in the HSB model) and L (in the HLS model) are set to the same value. Then, drag the B slider to reduce the brightness to zero. Now, reset the color value to #FFA7BCD7, and change the color model from HLS to HSB. As you do so, you will see the color-space cursor jog to the right, and then move straight down: Now, change the Blend color picker for the window background from RGB to HLS (by right-clicking on one of the R-G-B-A letters in the color picker) then, drag the L slider to reduce the Luminance value to zero. To see the difference, create a new WPF application in Expression Blend and set the window background to this solid color: #FFA7BCD7. Many developers assume the two models are the same, but that's not the case. HSB (Hue-Saturation-Brightness), also known as HSV (Hue-Saturation-Value) or.For that task, we can use one of two color models: The RGB color model works very well for most purposes, but it isn't well-suited to the task of calculating different shades of a color. Actually, the WPF Color object uses an ARGB color model, as it includes an alpha channel to control transparency. WPF works with the namespace, which includes a Color object built around the familiar RGB color model. However, I have included a sample IValueConverter class for each set of conversions. Instead, I focus on the conversion methods themselves.

I don't cover the IValueConverter aspect of the process in this article, since there are a number of good articles on how to create an IValueConverter class. Normally, the methods shown in the attached demos would be included in an IValueConverter object that is included in the data binding of the color property. This article explains how to perform the actual color conversion. So, after a bit of research, I determined how to perform the conversion in pure-WPF.

To me, mixing GDI and WPF is a code smell, which should be avoided in all but exceptional circumstances. System.Drawing is a GDI namespace, and I have a very strong preference for keeping it out of my WPF applications. I recently needed to perform this chore, and I was surprised to find very little on how to do the conversion without resorting to using the System.Drawing namespace. For example, we might calculate the border color as 85% of the background color. In cases where the color value is bound to another property, one would typically calculate the darker shade as a mathematical percentage of the base color. For example, we may want a button border to be a darker shade of the button background. WPF sometimes requires us to convert one shade of a color to another.
