![]() In the lower half, the saturation stays 100% and the brightness is decreased to 0%, which results in black. In the upper half, the brightness stays 100% and the saturation is decreased to 0%, which results in white. In the middle is each hue shown with 100% saturation and 100% brightness. The x-axis increases the hue from 0 to 360. Now we can draw the rainbow again and include some saturation and brightness variation. The color red drawn from 100% saturation to 0%: By incrementing this middle dot slowly from 0 to 255, we get all possible hues, for example, between red (FF0000) and yellow (FFFF00). It is this "middle" dot, which is not 255 and not 0 which defines the hue. For all other hues, the second strongest dot emits at less than 255. These, by the way, are the brightest colors a monitor can produce, since they use 2 dots fully turned on as opposed to red, green and blue, where only 1 dot is used. If we mix many painting colors together, we get something dark grayish and ugly. If we mix R, G and B shining at their maximum, we get a white light. For example, R 225, G 255, B 0 combines red and green and the result is ? Strangely enough, the result is yellow ! The reason is that when 2 lights shine on the same spot, the spot gets brighter not darker. We can produce hues at their purest when one of the 3 dots is 255, one is 0 and the "middle" (third) one can have any value. Hue assigns values for yellow, orange, red, etc. ![]() Interestingly, brightness is not defined from 0 to 255, but from 0 to 1 or 0 to 100%.Īnother property of a color is called hue. This is an example of changing the brightness of a color, one of the three properties every color has. Once R is 0, the resulting color is black, since no dot is emitting anything. If we want a darker red, we just lower the value of R. ![]() To see one of the primary colors, for example red, R gets set to 255 and the G and B to zero, which gives the brightest red possible. One dot can have a value between 0 (emitting nothing) and 255 (or 0xFF in hexadecimal) emitting at full strength. Of course, the "strength" (brightness) of these colors are rather limited when compared to other light sources as for example, the sun.Įach color is defined by how much light each of the 3 dots emits. With RGB pixels, a monitor can produce most colors a human eye can differentiate. The human eye has three different kind of receptors for colors and the colors (hue) of R, G and B are chosen to match well with these receptors, which happens to be the lime green and not the "normal" green. However, here is already the first misunderstanding, because in actual fact, G is not Colors.Green but Colors.Lime. Increasing Saturation and Brightness to 100% for Any ColorĬolor space HSB: Hue, Saturation and BrightnessĪs we probably all know, color on a computer screen gets created by pixels and each pixel consists of 3 dots which can emit the light Red, Green and Blue, which explains the names R, G and B of these dots.Getting Hue, Saturation and Brightness of a Rgb Color.Making Colors Brighter or Darker (Decreasing Saturation and or Brightness).Generating Your Own Color With Precision (Code of This Article).Color space HSB: Hue, Saturation and Brightness.If you already have a solid understanding of colors, you can just jump to the chapter, Generating your own color with precision, where the actual code is. 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. To explain how my methods work, I had no choice but to investigate in detail what is going on. Then I had the bad idea to write a CodeProject article. With this, I get nicely matching colors, a bit like gradients as in GradientBrush. 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. 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.
