How to Draw a Frog with Graphitint Pencils

green and white leafed plantsSummer is the time of bright colors, fun, and constant inspiration; there are so many subjects to draw and paint! Let’s use these recourses wisely and get the most of them.

I invite you to a new artistic journey. Today, we’ll dive into the world of sketching with tinted graphite pencils. Along the way, we’ll explore the advantages of textured paper and using toned paper instead of the customary white! We’ll also discuss ways to make your artwork more believable by including cooler and warmer colors.

Also, I’m going to show you some useful tips and tricks on transferring your sketch to your final drawing surface and dealing with any unexpected issues that may arise with this technique.

The main goal of this project is to capture the essence of the subject we’re drawing and creatively use our knowledge of color and light to create a fun drawing!

The Art Supplies for this Project

Let’s first take a quick look at the pencils.

I’ll be using pigmented graphite pencils made by Derwent – Graphitint pencils. I’ll be using several pencils from a set of 24 colors. These pencils are best described as a combination of colored pencils, watercolor pencils, and graphite drawing pencils.

Here are some of the unique characteristics of Graphitint pencils…

As opposed to ordinary graphite pencils, which are various shades of grey, each pencil is pigmented with color.

The colors are quite muted.

The pencils are water soluble – in other words, they can be activated with water, so the colors become richer and more intense.

After applying water or “activating”, the mark becomes very difficult, almost impossible to erase (unless you use a rough eraser that removes the paper as well). We’ll need to keep this in mind moving forward.

Although erasing after activating with water is nearly impossible, you can soften the intensity of the covered area by applying water once again and dabbing it with a paper towel or a brush.

The choice of paper also affects the behavior of the pencils. Thin papers tend to soak too much and may create unpleasant wrinkles.

If you think that activating with water may add some charm and vibrancy to your artwork, but the paper you use is relatively thin, it’s still possible to intensify the colors with a slightly wet brush. The paper won’t get too much water and the colors will become more intense. You can wet your brush and then slightly dry it with a paper towel before applying to areas of color. A damp brush will still activate the color.

I personally admire the range of colors that Graphitint pencils provide. There are definitely some wonderful greens and browns to choose from! This palette is perfect for creating animal and nature-inspired illustrations.

By the way, this is one of the reasons why I decided to draw a frog for this project, but we’ll touch upon this topic later.

I’ve chosen just seven pencils from the set to limit myself and keep a sketchy appearance. The names of the colors we’ll use are:



Ocean Blue

Autumn Brown


Cool Brown


Of course, you can choose more pencils for your drawing, if you wish!

Please note that the indications of color on the body of Graphitint pencils may not correspond to the actual colors we get on paper. That’s why it’s useful to test all of your pencils before applying them to an actual drawing.

Below you’ll find a sample of strokes made with the selected pencils. The strokes demonstrate the changes in pressure (lighter at the bottom, heavier in the middle) and the effect created by this variation. The top parts of the color swatches are activated with water.

I didn’t show the White pencil because the strokes are almost invisible in the scanned image.

This sample (above) was created on a relatively thick, textured watercolor paper. This sheet had a creamy-colored tint. Just a moment ago, we were talking about the difference in how the strokes look on various types of paper, so I thought that I’d share another example.

The sample below is made on a sheet of thin drawing paper that is more suitable for ink liners, ordinary graphite pencils, or any other dry media. As you may notice, the colors are less intense after applying water (in the upper portions of the color swatches), compared to the samples created on a thicker watercolor paper.

The color of paper affects the perception of the color. In the image below, you’ll find samples made with the same Graphitint pencils but now on green paper.

Derwent pencils are soft and require frequent sharpening. That’s why I recommend keeping a mechanical or an electric sharpener at hand.

A kneaded eraser is an excellent tool for softening lines and removing excess graphite. It may be useful to lighten the general contour lines of our final artwork but we’ll discuss this in detail in a moment.

We’ll also need an ordinary graphite pencil for sketching and creating a preparatory drawing.

It’s a wonderful idea to have some drawing paper for sketching, just in case you choose to play around with a few ideas.

For our final drawing surface, I’ve chosen Daler-Rowney Murano A4 paper (“Apple”). It has a very pleasant green tint and a subtle texture.

This paper may be found at your local art supply store. You can buy sheets of various colors and try many different options. The possibilities are truly endless!

I’m going to use only a portion of the paper. The remaining areas can be cut off and be used for sample sheets.

The Idea

My goal was to find something that has a greenish, greyish or brownish color. I also wanted a subject that features an interesting texture and has a connection to the theme of summer and nature.

A frog isn’t the only subject fitting the requirements, but I find it especially promising. The combination of the tinted green surface and beautiful, muted colors of Graphitint pencils create a perfect color for the pattern of the frog’s skin.

In this case, we get a great ready-made green background. The tinted paper sets the basic tone, we’ll just add the darker and lighter values!

The subtle texture of this paper produces a sketchy look which works well for this drawing. You can focus on other aspects other than just creating details and convincing textures. That’s why I recommend using this set of art supplies for drawing on location, directly from life. You may just find a real frog to draw!

I’ve already created a couple of drawings of a frog using the same tools – Graphitint pencils and tinted paper. Below you’ll find the examples…

The drawing we’ll create here will make a nice addition to the series that I’ve already begun.

Since I’ve already explored this subject in the past, I can choose the pencils with more confidence. One of the previous artworks was made on paper of this greenish tint (“Apple”), so I already know that warm browns work just fine.

The subtle inclusion of the reddish brown and purple should make this drawing more interesting and different from the existing artworks.

Exploring the Subject and Creating a Final Version of Your Sketch

I start the work with some abstract, conceptual sketching. This step is especially useful if you’re drawing an object that is not familiar to you. In these cases, reference photos may help greatly.

I create quick sketches of poses and anatomy studies using the HB graphite pencil. I’d like to find an interesting pose that is easily recognizable and not too complex.

A frog is a relatively simple animal to draw. It has a large head with big round eyes, a bulky body, and relatively thin limbs. The best approach is to draw the rough shapes first while imagining each shape as a three-dimensional form.

Even if your drawing isn’t perfectly accurate, thinking in terms of three-dimensionality adds to the believability of your art.

When I have a general idea of how my frog should look, I start a final sketch that will be transformed into the tinted graphite artwork.

After the general lines are drawn, I accentuate the significant contours and erase the marks that are no longer needed.

I also add a pattern of the frog’s skin. This allows me to consider where I should place the spots in advance.

The final sketch is complete, but how do we transfer it to our green paper?

The first option is to redraw it from scratch. However, the lines should be light and limited. That’s why this method may not be the best for everybody.

In the next part of the tutorial, we’ll explore a couple of ways to overcome this obstacle.

Basic and Advanced Tracing Tips: How to Transfer the Sketch to a Clean Sheet of Paper

There are several ways to copy a line drawing if we need to duplicate, improve, or create a new artwork.

1) Use carbon paper – This is a special paper that you may be able to pick up at a local craft or stationery store.

Put this paper under your sketch and place your finial drawing paper underneath the carbon paper. Outline your sketch once again on top of the existing lines and you’ll get a nice transfer on the final paper.

Usually this kind of paper creates a print that consists of dark lines, but there are also colorful copying paper variations (yellow, red, green, etc.).

The main advantage of carbon paper is the ease of use. The main drawback is that sometimes it leaves unpleasant marks that are difficult to erase and conflict with the materials you’re applying.

2) Use a light board or window – Another great way to transfer your line drawing to another piece of paper is using a window pane during the day or a light table.

First, put a new sheet of paper above the sketch and place them on top of the plane that lets the light go through. This makes the lines visible and you can trace them.
