Colors in that Apple:
Though it is very much correct to assume that the color of an Apple in red, but in reality, it is more complex than simply one red color. It’s a mixture of many colors. In this example, as the light source is falling onto the Apple from one direction, it forms a cast shadow on the paper, which is considered as the shadow developed by blocking the light source by the object and another one is form shadow which is developed due to not reaching light around the object. So we have found a range of colors ranging from darker to lighter from that same red color of that Apple.
Drawing The Apple:
Though the shape of the Apple is not a proper circle, I have started the sketching with a circle as a guideline. I have used a stainless steel glass to draw a very thin line with a 2B pencil. I have lightly sketched the form shadow and cast shadow areas as well.
Preparing The Paper:
As I am again using a 125gsm A4 size paper instead of canvas for this demo, I have a little bit of preparation before laying the first layer of color in the sketching.
I usually applied a thin coat of pure white paint to prime my paper first and let it dry. Which prevent the paper from absorbing further water in the process of painting. In case of a primed canvas, you no need to be worried about this things.
Laying Down The Color Layers:
For this demo, I have preferred using the primary colors like Cobalt Blue, Scarlet Lake, and Cadmium Yellow Medium. Zinc White is used for adjusting the values of other colors.
For the first layer, I have used a Yellowish Green tint using Cadmium Yellow with a pinch of Cobalt Blue. The same color is extended to the Cast shadow too.
Adding more Red to Yellow gives the more insense Orange tone. For a rough idea of the form of the Apple, I have applied a casual brush stroke with a size “9” flat nylon brush.
Shifting the color tint towards more Red now leads to Apple Red color. I have applied a slight mixture of Cobalt Blue with Red to achieve the darker shades of the Apple. It looks quite flat at this stage now.
In this stage tonal value is bringing down to those areas, where light reflections meet the Apple surface. In this case, the light reflected from the paper towards the lower side of the Apple and sunlight reflection towards the left side of the Apple. A small amount of White is used while the above surface was still wet to bring the value down. Further, I have worked in the background and the cast shadow with a Bluish Grey tone with the help of White, Cobalt Blue and a pinch of Scarlet.
In this stage, I am working on the stack with a darker color achieved through mixing Yellow, Red and small amount of Blue. More blending is done to remove the unnecessary brush strokes from the surface of the Apple. Further highlighting is achieved using White. One important observation in this example is that within the cast shadow itself we can see the reflected reddish color of the Apple near the base.
It’s time to add some of the detailing to this small painting. Like the Yellowish dots on the surface of the Apple, White spots on the stack, some lighter strands throughout the Apple surface, etc.
Though I am sticking to the primary colors during this entire painting demo, I will show how to use some ready to use colors for this type of painting to achieve more realistic colors rather easily.
For this type of painting, especially in Acrylic, there is no strict rule to follow. In this particular example, though I am using the yellow as the first layer, you can use red as your first layer. The final result will be the same.
