Adding color to a drawing doesn’t mean filling in lines like a coloring book. For me, it's about observing how color actually shows up in real life and using that to bring out form, light, and feeling.
The phrase “color drawing ideas” might make you think of techniques or prompts, but it can also be about how you approach color in your sketching practice—and how you move beyond that early stage of flat coloring and basic blending.
I rarely start with outlines. Instead, I build drawings from large shapes defined by light and shadow. I squint at my reference—whether that’s a photo or something in front of me—and begin with the biggest forms. Only later do I move toward the smaller shapes.
The same goes for color. I think about how patches of light shift in temperature, how reflected color sneaks into shadows, and how color adds mood and dimension, not just decoration.
If you're past the basics and want to deepen your expressive drawing with color, here's how I approach it.

Key Points
- Start your color drawings with large, abstract blocks of color rather than outlines
- Pay attention to color temperature, reflected light, and mood
- Let your color choices be expressive rather than “correct”
Color drawing ideas that focus on real light and expressive form
One of the biggest shifts in my own sketching practice came when I stopped treating color as an afterthought. I started observing the color of light first—the warm sunlight, cool shadows, or unexpected bounce light from nearby surfaces.
A white shirt in sunlight might be orange and blue, not just gray. A green leaf under a blue sky often has a purplish shadow. These subtle shifts are everywhere if you start noticing.
Here are some ideas to help you rethink color drawing:
- Use colored pencil or watercolor to sketch the largest shapes of light and shadow, not the outlines. Think of it like building with blocks of color instead of lines.
- Try drawing on toned or black paper to let highlights and color pop in different ways. Black paper forces you to think in terms of light, not just shadow.
- Practice drawing from real life objects under different lighting: midday sun, lamp light, overcast, etc. The same object can look dramatically different.
- Look at areas where color changes across a single object—a red apple might shift from crimson to deep burgundy to purple in shadow. Try to capture that range.
- Use unexpected colors to express feeling over realism—like a green shadow in a melancholy scene, or violet in skin tones during sunset.
You can dig deeper into the importance of light and mood in my article on color in drawing, where I go into temperature shifts, layering techniques, and tools.
Sketching with color on location or from references
When I'm drawing outside or from a photo I love, I don’t try to match colors perfectly. I try to suggest them in a way that adds life and energy. I treat colored pencils or brush pens like I treat a ballpoint pen: loose, expressive, layered, and imperfect.
Instead of trying to be exact, I look for color relationships. Is the shadow cooler or warmer than the light? Is there a hue shift between edges and center? That tells me more than any color chart.
Some practical ways to approach this:
- Sketch with just three colors and mix by layering (e.g., red, yellow, and blue pencils). This keeps your drawings cohesive and encourages creative thinking.
- Create drawings that start with color, then add lines after, or skip lines altogether. Reversing your usual order often leads to surprising results.
- Use watercolor in messy patches to suggest form, then define with darker pencil marks. You don’t need to be precious.
- Choose references where light is doing something interesting—like a cast shadow over a textured wall, or sunlight reflecting off a bright coat. Interesting light leads to more expressive color.
This is a good mindset to pair with looser methods I talk about in expressive drawing or when using a sketchbook for personal journaling, as I do in illustrative journaling.
Moving beyond coloring book habits
A lot of us learned to draw by outlining first, then shading or coloring inside the lines. That structure feels safe. But it also locks you into a flat view of drawing.
If you want to push past that stage, consider changing your sequence and letting color be the structure.
Here are some alternative approaches:
- Start with soft color patches, then draw your subject on top with a dark colored pencil or pen. This keeps the color from being trapped.
- Draw without an outline—just color shapes and let form emerge from contrast. This is how painters think.
- Try drawing on black paper using colored pencils to explore light and highlight instead of shadow. It trains your eye to focus on brightness.
- Limit yourself to no outlines for a week in your sketchbook—just build with light and color. It can be awkward at first, but forces growth.
There’s something freeing about not worrying whether something looks polished. If you’re too careful, it can kill your style. Some of my most interesting pages are messy drawings that started with wild color blobs and no plan.
Color tools I keep in my sketch kit
You don’t need a full set of supplies to experiment with color. In fact, I find that having fewer choices makes me more creative.
My basic kit usually includes:
- A warm red, cool blue, and golden yellow colored pencil (or water-soluble pencil)
- A brush pen or water brush to activate or smear pencil if needed
- A couple pieces of toned or black paper
- A white colored pencil or gel pen for highlights
- One bold color (like teal or orange) to throw into shadows and break monotony
I often use these with the same observational techniques I describe in analytical drawing—but with a looser hand. I’m not trying to be scientific, just mindful and expressive.
Sketchbook prompts to try
If you want to play around without pressure, these sketchbook prompts can help shake things up. The key is to focus on what you observe, not what you imagine should be there.
- Draw the same object (like a cup or shoe) under warm and cool light, using colored pencils. See how temperature shifts perception.
- Pick a single color family (like blues) and draw a scene using only variations of that color. This creates mood and focus.
- Go outside at sunset and draw only the color shapes of the sky and shadows. Don’t worry about form, just color blocks.
- Use one color to describe both light and dark—press harder for shadow, lighter for highlights. A single pencil can do more than you think.
- Draw a portrait with no outlines, just using patches of color to describe form. Let edges appear from contrast, not lines.
You can find more sketchbook-specific prompts in my breakdown of sketchbook challenge ideas or these drawing ideas.
If you’re interested in building this type of observational practice, I also recommend checking out drawing with ballpoint pen techniques or how to start sketching without fear of mistakes.
Where to find inspiring real-life color
One of my favorite sources for color inspiration is nature. If you're not sure where to start, try sketching birds. Their feathers often contain surprising color shifts and lighting effects that go unnoticed until you start drawing.
Even sketching a basic pigeon or crow can reveal beautiful cool grays, iridescent greens, and violet shadows.
The Getty Museum’s drawing collection is also worth browsing for how classical artists approached color in subtle ways—many used limited palettes to powerful effect.
Sometimes I also return to foundational concepts through creative drawing exercises or revisit techniques I used when learning how to draw a scene, especially when layering color for storytelling.
Exploring color in your drawings isn’t about mastering every medium or theory. It’s about seeing more. Looking closer. Letting color become a way to express light, emotion, and movement in a way that goes beyond coloring inside the lines.
