In this lesson video, we are going to cover different methods of adding shedding colors to our flat base color. First, let's create a circle or selection. To do that, click on the circle selection tool in here. Click drag to create the selection and while dragging, hold Shift to make a perfect circle. Okay, now pick a light gray color, then hold shift and then Backspace to fill the selection region with the light gray color we pick before. Now we have this flat colored circle.

To clear the selection, we can press Q electoral key. Remember that we have changed the shortcut for clearing selection to Q letter key in a previous video. Okay, so basically our job here is to make the circle to look like a sphere by adding shading to it. So how can we do that? Well, there are at least two methods to do this. The first method is by using large soft brush and the second method is by using hard edge brush, but then we use the blur brush to blend the colors.

Let's see how we can share the sphere using the first method. But before we can do any shading works, the first step to shading is to determine the light sources. Complex illustrations may have multiple light sources. When we add shading, we need to consider all of these light sources. For this first step tutorial, let's just use one simple light source. Imagine that we have a light source at the top left area of our sphere.

So this area will be bright and this area will be dark. Okay, the first method is to use soft large transparent brush to shade the sphere region. To do that, make sure the brush tool is active and let's make these airbrush brass preset next Change the brush size to be about the size of the sphere area. We can do this by holding Shift and then click drag to the left and to the right side. Okay, next, select darker color by pressing k letter key three times. Remember K is for darker color and L is for brighter color.

Now, if we just brush away like this, we will have the shading colors all over the place. We only want to have the shading color on the existing circle area, not everywhere. So in order to do this, let me undo First, we need to turn on the alpha lock in here. Okay, now with this turned on, if we draw some brushstrokes, they will only affect the pixels colors, but maintain the existing pixels opacity. Okay, let me undo this again. Now to turn this fat circle to looks like a sphere.

Do some strokes like this round like this several times from inside to outside, the airbrush brass will produce stroke thickness or opacity based on how hard we put pressure on the pen. Remember, the light source is at the top left area. So this means that the right bottom area should be dark. Now, if you are very new to digital painting, this is a very good practice to start with. If you fail at your first attempt, just fill the circle with a light gray color like before, and just try and try again until you like the result. The more you practice, the more you get the hang of it.

Okay, now to add highlight. Let's pick our original base color first by pressing Ctrl key and click on this area. We can pick brighter color against our base color directly from the color picker in here or by pressing ng l keyboard shortcut several times, then make the brush size smaller. Now beside holding SHIFT and click drag like before, we can also use the bracket keys for changing the brush size. So press the opening bracket key several times, and then just draw a stroke, make the brush size smaller again and then grow again and so on. We should have this nice sphere growing.

As always, if you failed at the first try, just undo and try again, practices will make you better and better at it. Now let's explore another method of shading which is using the solid brush and the blue the brush tool. This time we will also going to explore a different method of layer organization which is basically using a dedicated layer for shading. This way we have more flexibility to tweak it further. Let's hide this layer, create a new layer. Okay, now let's create another circle, but this time we are going to use the Ellipse Tool instead of the selection tool, so click on this tool.

In the tool options, make sure the fill option is set to foreground color and the outline option is set to no outline. In the color picker, make sure we set the color to a light gray color. Then click drag and hold Shift when dragging it to create a perfect circle and we have a flat gray circle. For the shading, we are going to create it on a separate layer on top of this layer. So create a new layer. Let's just rename these two layers first, so we don't get confused later.

Rename this top one to shading, press tab and this one to base. Okay, we need to constrain these top layers opacity to this layers option. acity in Krita we can do this if both of these layers are inside the same group. To do this quickly, first select this one, hold Ctrl or shift and then click on this one. So now both of them are selected then press Ctrl G As we can see, now both of these layers are inside a group to make these shedding layer constraint to this base layer simply turn on the alpha inheritance button in here. In this way when we draw something in a shading layer, it will only appear when it is on top of the circle in the base layer.

Okay guys, so this is a different approach which is a non destructive way of adding shading to a base color growing. Now we are going to actually create the shading colors. Previously we used airbrush brass preset to add shedding color. Now we We are going to use this solid or a flat brush preset called basic five size. Change the size to be about as big as the base circle but decrease the opacity to about 20%. hold Control click inside the circle area to sample the existing base color.

Then press k three times to get way darker color from the original base color. Then create a round brush strokes like this and fill the entire right bottom area. Do that again. But now we start from this round area towards the dark side and then again and add another one. We now have multiple flat color regions like this. To blend all of these colors together.

We can use the blender blur Brush Preset, make the brush size bigger to more or less the size And then just stroke like this to blend in the colors. Okay. Now sometimes we want to move or shift colors from one to the other location. We cannot do this with the blender blur brush, but we can do this using this Brush Preset called the blender smear brush. using this brush is like having our hand or finger to move around with pains. Okay guys, so those are the two methods that we can use to add shading.

Of course there are other methods that we haven't covered yet, but I believe these two methods are great starting points.
