![]() The easiest way to see the differences in Chroma and Saturation in action is to duplicate your main image layer by clicking on the “duplicate” icon (circled in red in the image above). light), but different chromas if the purity of red differs between the two colors. When a color’s Chroma is changing, the purity of its color is changing. red), but different values if one color is lighter than the other. When a color’s value is changing, its lightness or darkness is changing. For instance, when a color changes from red to green, it’s hue is changing – red and green are hues. When you compare Chroma to other color measurements, such as Hue and Value, it can be distinguished in the following sense: the hue of an image will change as you move around the color wheel. So, in this case, you can see that saturation can actually be a component within Chroma. To put it another way, Chroma is “ how much of a pure hue is present” in an image (according to ).Ĭhroma can also be defined as “the quality of a color’s purity, intensity or saturation” according to. When comparing Chroma directly to Saturation, the easy way to understand the difference between the two is this: Saturation is the intensity of a color (as stated above), and Chroma is the purity of the color. However, it is new in the sense that it can now be paired with the Chroma adjustment). With this tool, you can again adjust the “Hue” of the image, but you can also adjust the “Chroma” and “Lightness” of the image as well (lightness is actually another setting found in the Hue-Saturation tool, so this is not a completely new feature. This will open up a dialogue box with 3 different options. ![]() You can access this by going to Colors>Hue-Chroma. In GIMP 2.10, a new Color Tool is introduced called the “ Hue-Chroma” tool. If you’ll remember in the “Hue and Saturation” lecture from earlier in this course, adjusting the “Hue” slider when using the Hue/Saturation tool will change the overall color of an image, and adjusting the “Saturation” slider will change the intensity of the colors within the image (i.e. In technical terms, an image’s “Hue” is the wavelength of the color in the image, whereas the “Saturation” of an image is the intensity of that color.
