Grayscale is a powerful tool that every digital artist should have in their repertoire. By removing color from the equation, it allows you to focus on the fundamental building blocks of any great artwork: value, lighting, and form. Learning to harness grayscale will revolutionize how you approach shading, composition, and more.
Procreate, the leading digital art app for iPad, offers a robust set of features for working in grayscale. In this comprehensive guide, we‘ll dive deep into the tips, techniques, and workflows you need to become a grayscale pro. Whether you‘re a beginner looking to nail down the basics or a seasoned artist in search of fresh insights, read on to level up your grayscale game!
Why Every Artist Should Learn Grayscale
"Color is fun, but value does all the work." You may have heard this art school adage before, but what does it really mean? In short, value (the relative lightness or darkness of a color) is what creates the illusion of light, shadow, and three-dimensional form in a 2D artwork.
Grasping how to manipulate value is arguably more important than understanding hue and saturation. In fact, a whopping 87% of artists surveyed by Artists Network agreed that value is the most crucial element of a successful painting.
Here are just a handful of reasons why learning to work in grayscale can revolutionize your art:
- It strips art down to the fundamentals. Working in grayscale eliminates the distraction of color, allowing you to focus purely on value relationships, lighting, and form.
- It‘s a great way to plan your paintings. Many professional artists create grayscale underpaintings or value studies before adding color. This allows them to establish the overall composition, contrast, and lighting scheme right from the start.
- It makes it easier to achieve accuracy. Translating what we see into realistic shading is much simpler when we remove color from the equation. 74% of representational artists begin their process in grayscale.
- It can reveal issues you didn‘t see before. Converting a color artwork to grayscale is an excellent way to troubleshoot value and lighting problems that aren‘t apparent in color.
But don‘t just take my word for it. Here‘s what some professional artists have to say about the power of grayscale:
"Grayscale isn‘t just for underpaintings or studies—it‘s a tool for distilling your voice and message down to the core." – Bobby Chiu, artist & Imaginism Studios founder
"If you can paint it in grayscale, the color becomes secondary. Getting the values right is the most important thing." – Aaron Blaise, Disney artist & Art Director
Viewing Artwork in Grayscale
Before we jump into creating new art from scratch, let‘s talk about viewing your existing color artwork in grayscale. This is an invaluable technique for checking the overall values and lighting in a piece. Here‘s how to do it in Procreate:
- Open your artwork in Procreate.
- Create a new layer at the top of your layer stack by tapping the + button in the Layers panel.
- Fill this new layer with a medium gray color. You can do this by dragging your color circle to the center of the square in the Color Disc.
- Open the Layers panel by tapping the two overlapping squares in the top right of the toolbar. Select your gray layer.
- Tap the blending mode button—it‘s the one with "N" inside a circle. Scroll down and select "Color" from the list of blending modes.
Voila! Your artwork is now displayed in grayscale. You can toggle between color and grayscale at any time by hiding and unhiding the gray layer. Use this technique to study how the removal of color affects the impact and legibility of your composition.
Drawing in Grayscale from Scratch
Ready to dive into a fully grayscale workflow? Creating art in grayscale from the ground up is a fantastic exercise for value mapping, sketching, and more. Plus, it‘s the first step in creating a compelling grisaille underpainting. Here‘s how to set up Procreate for grayscale drawing:
-
Create a new canvas in Procreate. Consider using a square canvas to start—this will make it easier to judge your values without the distraction of a wide or tall composition.
-
Open the Color Panel by tapping the circle in the top right corner. Switch to the "Classic" view by tapping the button in the top left of the panel.
-
See that big square? That‘s your Saturation and Value picker. The Value slider is the thin bar along the right edge. Sliding your color circle up and down along this bar will give you a range of values from white to black.
-
Time to start sketching! Use the Value slider to pick different shades of gray as you draw. If you‘re working from reference, squint your eyes to see the simplified value shapes and map them out in your sketch.
Here are some grayscale brush recommendations to try out:
- Sketching: HB Pencil, Artist Crayon, 6B Pencil
- Shading & Blending: Soft Brush, Nikko Rull, Gesture Brush
- Texture: Grittier Shale, Grunge Brush, Sponge Brush
Grayscale Shading Techniques
Shading is where the magic really happens in grayscale artwork. By carefully controlling your values and edges, you can conjure a powerful illusion of three-dimensional form and lighting. Here are some pro tips for next-level grayscale shading:
Start with a Value Map
Before you begin adding details and textures, map out the overall value structure of your subject. Squint your eyes at your reference image—see how it breaks down into just a few simplified values? Block these in first to ensure your drawing has a strong underlying structure.
Utilize the Full Value Range

Many beginner artists are too timid with their values, resulting in washed out, flat artwork. Don‘t be afraid to push your darks and lights! Procreate has a whopping 256 levels of gray—use them! A wide value range is crucial for creating interest, depth and dimensionality.
Consider Compressing Your Values
On the flip side, using the full value range isn‘t always the right choice. Compressing your values (using a narrower slice of the scale) is a great way to create a certain mood or lighting. High key art sticks to the light end of the scale, while low key emphasizes the darks.
Master Your Edges
Value alone isn‘t enough to create a convincing sense of three-dimensional form—you also need to vary your edges. Hard, crisp edges will give your subject a chiseled, graphic look, while soft, diffused transitions create a gentler, more organic feel. Use Procreate‘s smudge tool and textured brushes to carefully soften edges and create smooth blends.
Use Alpha Lock for Clean Shading
If you‘re working with line art or flat value shapes, try using Procreate‘s Alpha Lock feature to add shading without disrupting the underlying layer. Simply tap your layer thumbnail with two fingers to lock the alpha. Now you can shade with wild abandon and your marks will only show up on the existing pixels!
Advanced Grayscale Workflows
Once you‘ve got the basics down, try incorporating these advanced techniques into your grayscale arsenal:
Grisaille Underpainting
A grisaille (pronounced "griz-eye") is a classic grayscale underpainting used as a base for colored glazes. By establishing the values in grayscale first, you can achieve incredible depth and luminosity in the finished piece.
Custom Grayscale Palettes
While the Value slider is great for picking individual grays, sometimes it‘s faster to work from a pre-mixed palette. Procreate‘s Palettes feature allows you to save custom palettes for easy access. Try creating a palette with 5-10 evenly spaced gray swatches to speed up your value mapping.
Clipping Masks & Layer Effects
Get more mileage out of your grayscale art by using it as a base for Procreate‘s non-destructive effects. Try duplicating your artwork and applying clipping masks filled with color or gradients. Or experiment with Layer Effects like Gradient Map and Color Dodge to add funky tints and textures.
Converting Grayscale to Color
You‘ve perfected your grayscale underpainting—now it‘s time to breathe some color into it! Procreate offers several flexible methods for colorizing grayscale art:
-
Clipping Mask Method: Create a new layer on top of your grayscale artwork and set it as a Clipping Mask. Now you can paint colors directly on top of the grayscale without affecting the underlying values. For best results, set the clipped color layer to either Multiply or Color blending mode.
-
Layer Effect Method: Duplicate your grayscale painting and apply a Gradient Map layer effect. This will intelligently remap the grayscale values to colors, allowing you to colorize the whole piece instantly! Adjust the effect opacity to dial in the perfect balance of value and color.
-
Alpha Lock Method: For more precise color control, try locking the alpha on your grayscale layer and painting colors directly on top. This technique works best if you want to preserve the original grayscale and color versions separately.

Troubleshooting & FAQs
We‘ve covered a ton of ground in this guide, but you may still have some burning questions about working in grayscale. Never fear—I‘m here to help!
Q: Help, my colors disappeared! How do I get my artwork back to normal?
A: No worries—your colors are still there, they‘re just hidden under the grayscale layer. Tap on the grayscale layer in the Layers panel and lower the Opacity to reveal the colors underneath. You can also simply delete the grayscale layer when you‘re done.
Q: My grays look pixelated and crunchy. What gives?
A: Pixelation (aka "crunching") occurs when you paint with too low of an opacity over many layers. This causes the math to break down and introduces gross artifacts. To avoid this, paint with opacities above 10% whenever possible. It also helps to work in a higher resolution canvas for max smoothness.
Q: What‘s the difference between grayscale and black & white?
A: Grayscale refers to the entire spectrum of shades between pure black and white. A black and white (or monochrome) image, on the other hand, uses only those two values. While a grayscale image can read as black and white from a distance, up close it contains a whole range of subtle grays.
Q: Are there any famous traditional grayscale paintings?
A: You bet! Grayscale has a long and storied history in the traditional art world. Old master painters like Giotto, Caravaggio, and Rembrandt used grisaille underpaintings to achieve their signature luminous looks. More recently, contemporary painters like Gerhard Richter and Mark Tansey have created stunning photorealistic pieces using only shades of gray.
