It's a structural color, which means it comes from special properties of the material. Interestingly, it doesn't have anything to do with the pigment. Remember to leave blackness in the shadow and to treat these reflections like any other specular reflection in terms of color and brightness! Iridescence To achieve this effect, shade with a scattered or textured brush. The reflection is going to be quite diffuse! Once again imagine the thin, transparent, glossy layer, but this time make it not so perfectly smooth. This is certainly the most popular kind of reflection when it comes to black materials. A red layer, on the other hand, will react to a white light by reflecting red only, and it will not reflect green or blue. A white layer will be able to reflect every color, though they will be quite dark unless they come from a light source. The color of that reflective layer is important to determine what and how it's going to reflect the environment. Treat a glossy surface like a mirror reflecting only bright things and making them darker The brighter the reflected object, the brighter the reflection. You can use a soft, round brush to reflect such an area on the black surface. Pay attention to other elements in the environment that reflect light very strongly, like a white floor. Then use a hard brush to paint a reflection of the light source-the smaller, the better the effect. To achieve this effect, start with a black (or very dark) material. That layer stays invisible until it's given something bright to reflect. You can imagine a matte black material that has a thin, transparent layer on top. This kind of reflection is easy to recognize, because it moves when you move. If a material is supposed to be dark, make it dark! Specular Reflection Don't compare it to more contrasting elements of the picture. Then you can shade it normally, bringing it to almost black in the shadow, but not any brighter than that base in the light. To achieve this effect, first define the brightest version of this color. It applies to situations where the object is dark even in full light, but it still has certain hue and saturation. This is the most basic one, but it's not the most popular in the case of dark surfaces. There are a few ways that let us see "black" objects: Diffuse Reflection This dim light is what we see when looking at a dark object. Dark surfaces usually reflect 15–20% of light, but they still do it. However, none of the objects we observe on a daily basis is truly black. That's the definition of black-we can't see it. This is actually a gray ball, the color of which is revealed by light. It doesn't reflect anything, so it doesn't care about the amount of light hitting it (or not). When light isn't that good, or it can't hit a part of the object, the color gets distorted. The general rule is that perfect, 100% bright and pure light reveals the "true" color of the object. If something becomes gray in light it means it was already gray! However, it's not really about light hitting the area-it's about how the area reflects it back to our eyes! And since black doesn't reflect anything at all, it can't reflect more light as it gets illuminated. Therefore, we make the black ball black in the shadow, and then we make it gradually brighter as it's touched by light. The more light hits the area, we think, the brighter it looks. The premise of form-emphasizing shading is that an object is hit by various amounts of light depending on how each part is located towards the light source. It gives us a proper 3D form, and may look all right as an element of many styles, but is it how it works in reality? The Secret of Black The most intuitive method is to make the shade brighter in the light and darker in the shadow. We all know that's not the case, so we shade these balls anyway. But if it were that simple, we wouldn't need to shade these objects at all! A white ball would look like a white circle, and the same with a black ball. Black objects, on the other hand, are unable to reflect any light at all. If you want to learn how to shade very dark and very bright objects, especially in terms of living creatures and realistic lighting, keep on reading!Īs you have probably heard, white objects are capable of reflecting all the light hitting them. All those hues with different saturations and brightnesses can make you dizzy! Black and white, in this case, should be much less complicated, but that's not true at all. Shading with colors is not an easy thing.
