It’s that time of year again.
(For those of you who've forgotten, I’m talking about Valentines day!)
And I know what a bunch of romantic folks you are, so in this step by step tutorial I’m going to show you how to paint a rose in watercolor. I’ll go over all the details so you can understand the process from beginning to end.
What better way to paint this weekend ?!
Flowers are a favorite subject for a lot of artists but the forms of roses are particularly complicated, which can sometimes make painting these flowers a challenge.
If you want you can follow along and paint your own version of this composition. All the reference material and the sketch template can be downloaded below.
And who knows, you could end up with the perfect valentines gift (psst… if you forgot to order flowers, all is not lost!)
How to Paint Roses in Watercolor
Roses are fairly complex looking flowers which can make them seem difficult to paint.
The sketches below simplify the anatomy of a rose into basic geometric shapes. Understanding the structure like this will help us to figure out how it interacts with light and shadow.
The overall form of a rose can be compared to a cup.
The center of this cup contains a series of smaller closely packed petals that make up the inside of the rose.
The outside of the cup is surrounded by bigger petals which progressively curve outwards and unfold.
When you draw these three basic elements you start to get something which resembles a rose.
As a general rule when a rose is lit from above, the upper part of the rose will appear lighter than the bottom part.
Also, because of the way the petals converge towards the center of the rose, each petal will look lighter at the tip and get progressively darker as it reaches the heart of the flower.
The combined effect is that the tonal values of a rose get progressively darker from top to bottom (light at the top and dark at the base), and from the tips of the petals towards the center as they gradually become hidden from the light.
Simply keeping these ideas in mind about how the light and shading changes across the surface of the flower is enough to be able to paint a reasonable interpretation of a watercolor rose without even trying to copy the subject exactly.
Watercolor Rose Sketch
Before tackling the final painting I did a quick watercolor rendering, following the “tonal value rules” we just described.
First I sketched a freehand version of a rose which approximates the geometry of the flower, with tightly spaced petals in the center and larger unfolding petals on the outside.
The idea is to do a loose painting as a warm up for the final watercolor, so I’m not trying to be very accurate with my brush strokes and at the same time I can test out my paint mixtures.
I begin with a very light and diluted pink color, charged with some yellow for a bit of variety.
I paint the petal shapes, keeping in mind the overall rules for shading. You can see that I try to leave some white highlights for the tips of the petals where they would be the most exposed to light. And I make the inner folds of the petals darker because these are the parts which are the most shaded.
I use a glazing technique to add more layers of paint to strengthen the values of the underside of the rose which would logically be more shaded. And I leave the petals at the top and on the outer edges light in color. A single layer of diluted paint is enough for these shapes.
As a final touch I add a few brush marks of darker paint to the most shaded parts of the flower, such as the folds on the lowest petals, and the core of the rose which is generally quite dark because of the concentration of closely spaced petals in the center.
I’m not really worried about blending edges at this stage. I just want the overall tonal values to look approximately right.
I added a quick background using a contrasting green color to help the flower stand out on the page.
I find it can be useful to do a loose watercolor sketch like this before you commit to the final painting. It’s a good way to familiarize yourself with a subject.
Watercolor Rose Step by Step
Here are the paint colors I used for this project (links to Amazon):
This is the reference photo I chose for my final rose painting.
Begin by transferring the outline of the rose onto a sheet of watercolor paper and tape it down to a flat board using masking tape.
I begin painting the flower from the center outwards using a medium strength mixture of quinacridone rose. (You’ll find a list of all the colors I used for this painting below).
I applied my first brush marks to the inner folds of the petals where they are darkest in tone, then using a rinsed and blotted brush, I blended the color outwards to become lighter at the tips. You can use the reference photo as a guide to help you with this.
Keep working from the middle outwards using the same method. You can also charge in some different colors such as warmer reds or yellows to add some color variation.
When you reach the outer petals towards the bottom you should adjust your paint mixture so the petals appear shaded. To do this added a small amount of french ultramarine to make a purple-violet color.
In the real world, outdoor lighting tends to be warm, which produces shadows with a cool blue-violet appearance. The result will be much more colorful and realistic than if you try to use a dark colored paint such as gray or brown. Brown is too warm and will produce the wrong color for shading and shadows in this situation.
Continue painting the outer petals at the top of the flower, but of course this time you need to use a diluted light-toned pink color. As you can see in the reference photo the very top of the rose is brightly lit.
As you progress downwards you can use stronger colored paint. I’m working using mostly a wet-on-dry technique. I apply brush marks directly onto the dry paper, then I rinse my brush and blend out the edges to get a smooth gradient of color from dark to light. Just make sure your brush isn’t too wet when you start blending, or you might flood the existing wash and cause unwanted stains known as “blooms”.
I use stronger colors as I reach the bottom of the flower, and I also drop in some additional color in places where the paper is still wet. This is a wet-on-wet technique known as “charging-in”.
Let the paint dry then go back over the parts that need stronger values such as the center of the flower and the petals on the underside which are in shadow.
Leave the paint to dry again. You’ll find that watercolors appear lighter when they dry, so repeat the layering process once again to increase the tonal values for the darkest folds of the petals.
Repeat this process as many times as needed until you’re happy with the overall result.
Now that the flower is complete you can move on to the leaves and the stem.
I painted these in a very loose style. I didn’t want to add too much detail to the leaves because these are not the main focus of the painting.
I paint these using quick brush strokes without trying to be too accurate. While the shapes are still wet I take advantage to either drop in different colored greens or use a dried brush to blot up the paint. The objective is to create loose leaf shapes with variation in tone and color.
When the first layer of paint is dry I added a few quick brush strokes to add some texture to the leaves. Nothing too precise, just a suggestion of the kind of patterns you find on leaves.
And here’s the finished painting…
