Also note how the darkened eyelashes make theĮyes stand out even more by introducing a strong value contrast! The next thing that Somewhat lighter area around her upper cheek even though the contrast is not as high Here is another exampleĪbove, the focus immediately jumps to the eyes, which stand apart from the This difference in contrast doesn’t even have to be so strong. Only from there do yourĮyes wander to the other details of the scene. With the dark background, and the rest of the image in general. Looking at the above image, regardless of where you start out, you’ll find yourĮyes sort of sinking down to the bright flame area, which has a strong value contrast Values next to each other tends to immediately draw the eye to those points in an Placing elements with strongly-contrasting Sense of depth remains this is because the values are consistent with the As you can see, regardless of the hue used, the With a random hue, but pick values from a value scaleīased on the grayscale level. For each pixel in the image, I replace it When it comes to giving a sense of depth. Here’s another example showing that value is the most important aspect of color These three values it gives the image a sense of depth. Here’sĪn example of a generative portrait I made a while back usingĬonsists of just three values: white, black, and a middle gray. It’s what we see when we look at a grayscale version of an image. Gradations of value create the illusion of depth. Used to create a strong focal point within an artwork. First, changes in value are whatĬonfer an illusion of depth to a painting, and second contrasting values can be There are two big reasons why values matter. Here are some very simple examples of the kinds of effects you can get out of these Now that we’ve looked at how to create value scales programmatically, Monochromatic palettes in a more structured way! To do the trick well enough for what I wanted!Ĭolor hsbValueScale ( float hue, int n ) Īnd that’s it! You can now play around with different value scales and explore However, I found the following little function There are many complex ways to get perceptually equidistant values using complexĬolor models like HSL or LCH. We need is a variation in both the saturation and brightness channels in Therefore, to programmatically generate value scales, what Of value requires taking a color from white all the way to black with a pure hue When referring to it as HSV), is not the same “value” that we’re after. Unfortunately, this also means that the brightness component of HSB (or “value” Saturation as adding white to a pure hue, and lowering brightness as adding Need to first understand the relationship between hue, saturation, andĪ simplistic, but effective, way to think of how these relate in HSB is to think of lowering To procedurally generate color value scales, we Some examples of value scales for some colors: In fact, each color (or hue) can have the full range of values as well. Now what’s important to note is that value is independent of the color itself. Number of steps going from white to black, and this is called a value scale.īelow is an example of a gray-value scale with ten steps: The lightest value, while black is the darkest. Value refers to the lightness or darkness of a particular color. Let’s first understand the concept of value itself. To monochromatic color schemes involves building value scales. Rather than randomly varying saturation and brightness, a more structured approach Side is that they have a very low degree of hue contrast: they tend to be reserved In fact, they have the highest degree of harmony possible. Since they use just a single hue, monochromatic colors are guaranteed to be Of the HSB color space as a cylinder, we’re looking at the different colors onĪ single sliced side (as highlighted by the black rectangle below). When looking at S+B variation in a previous article. In fact we’ve already encountered monochromatic colors Monochromatic colors are those where just a single hue is used and only saturationĪnd brightness are varied. Saturation and brightness canīe independently varied while still maintaining a sense of harmony. Note: when talking about color harmonies, it’s important to note that we’re talking Harmonies: monochromatic, analogous, complementary, split-complementary, warm-cool, triadic, and tetradic.Īs a preview, here are what these harmonies look like: We’re going to start exploring some of the more common color Now that we have our RYB color wheel set up,
