Our Anime Coloring Workflow

Every anime-style illustration that leaves ILUZTAR goes through the same four stages, whether it is a small headshot for a profile picture or a full-body scene with a detailed background. That consistency is deliberate. When the process is predictable, the quality becomes predictable too, and clients always know what they will be asked to review and when.

This post walks through each stage in the order we actually work: what happens, what we are looking for, and where a client's feedback matters most. If you have ever wondered why an artist asks you to approve a rough sketch before anything else, the answer is in the first section.

Why a fixed process at all?

Coloring an illustration is a chain of decisions, and every decision leans on the ones made before it. A shadow only makes sense once the light source is known. A light source only makes sense once the pose and camera angle are settled. If we change the pose after shading has started, most of the shading has to be repainted. A fixed order protects both sides: we do not waste hours on work that will be thrown away, and you do not pay for revisions that could have been avoided with one earlier check.

The cheapest time to change something is before it has been painted.

How we plan every piece

1. Sketch and lineart

We start rough on purpose. The first pass is only gesture and proportion: where the weight of the body sits, how the head turns, what the hands are doing, and how much of the canvas the character occupies. At this size, details are distractions. A pose that reads clearly as a tiny thumbnail will almost always read clearly as a finished piece; a pose that only works once it is detailed usually does not work at all.

Once the composition feels right, we send it to the client. This is the most important review in the whole commission, and we would rather you spend five minutes on it than five seconds. Is the expression right? Is the outfit correct? Is the character holding the right item? Every one of these is a quick fix now and an expensive one later.

After approval, the sketch is refined into clean lineart. Line weight does a lot of quiet work here: thicker lines on the outer silhouette and on the side facing away from the light, thinner lines for interior details such as fabric folds and hair strands. Good lineart already suggests depth before a single color goes down.

• Gesture and proportion first, details later
• Client approval on the rough sketch before refining
• Line weight planned around the light source that will come later
• Clean, closed shapes so the coloring stage is fast and accurate

2. Base colors

Next come flat colors: one solid color per material, with no shading at all. Skin, hair, each piece of clothing, metal, leather, and so on each get their own layer. This stage looks plain, but it answers a big question early: does the palette work?

We check the flats in two ways. First, we zoom out until the character is small and make sure every major shape is still readable by color alone. Second, we look at the piece in grayscale. If two neighbouring areas collapse into the same gray, they will fight each other once shading is added, so we adjust the value now rather than later.

If the character already has an established design, this is where we match the reference exactly. If the palette is new, we usually build it around the mood of the piece: warm and saturated for something energetic, cooler and more muted for something calm or mysterious.

3. Shading and highlights

This is where the illustration starts to feel three-dimensional. Anime coloring leans on cel shading: clean, hard-edged shadow shapes rather than soft gradients. Hard edges keep the look crisp and readable, and they force us to design the shadow shapes instead of simply airbrushing darkness onto a form.

The light source was decided back at the sketch stage, so the shadows fall consistently across face, hair, and clothing. On top of the main shadows we add a second, smaller layer of darker accents in the deepest folds, then highlights on hair, eyes, and reflective materials. Rim light, a thin bright edge where light wraps around the silhouette, is one of the most useful tools here: it separates the character from the background and makes the whole figure feel lit rather than colored.

• One primary light source, chosen at the sketch stage
• Hard-edged cel shadows designed as shapes
• Darker accents only where forms really meet
• Rim light to separate the character from the background
• Highlights used sparingly so they keep their impact

4. Effects and finishing

The final pass is what turns a technically correct drawing into something that feels alive. Glow and bloom around light sources, particles, atmospheric haze, and a final round of color grading all happen here. Color grading is subtle but powerful: shifting the shadows slightly toward blue or purple, or warming the highlights, can change the whole emotional temperature of a piece.

We also do a last technical check: stray pixels, gaps in the lineart, layers that were left slightly misaligned, and the edges of the canvas. Then the files are exported at full resolution in the formats agreed at the start of the commission.

Where you are involved

Clients are not expected to follow every stage, but there are two points where your feedback carries the most weight. The first is the rough sketch, where pose, expression, and composition are locked in. The second is the flat color stage, if the palette is new or has to match an existing character. After that, changes are still possible, but they take longer to redo, which is why larger changes at the rendering stage can carry a small extra fee.

Tools of the trade

All of this happens in a small, deliberate toolkit. Each program is used where it is strongest:

• Ibis Paint for sketching and lineart, especially when working away from the desk
• Clip Studio Paint for detailed rendering and brush work
• Adobe Photoshop for compositing, color grading, and final effects

Software does not make the decisions, though. The same four stages would work in any program. What makes the result consistent is the order, the checks between each step, and a client who has seen and approved the foundation before the finish is painted on top of it.
