I would have expected that white and black would mix too and that the bottom right corner would be gray. Basically, I wanted to change the color on the y axis (top to bottom) from red to black, meaning the brightness from 1 to 0, and on the x axis (left to right) from red to white, meaning saturation from 1 to 0. I guess this is the most confusing picture in this article. The color red drawn from 100% saturation to 0%: Example: Present value: R 255, G 128, B 0 Decrease saturation from 1 to. To decrease the saturation from 100% to 50%, we have to half the difference between the present value to 255. If we want to make a fully saturated color brighter and bring it finally close to white, we need to lower the saturation by increasing the intensity of all three dots proportionally closer to 255. So far, we have dealt only with fully saturated colors, i.e., the darkest dot was 0. The third color property is called saturation. Hue is defined in degrees with red being a 0 and 360 degrees. For this reason, the rainbow is often drawn as a circle. On the left and right end, there is each time a red. 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. Color 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. 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 an article about this. 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.
