Flat colors cute, then you shade and the face looks tired or grey? You’re not alone.

Hey! I'm Linda from Scribling Art 👋

This is my fast five-block workflow in Clip Studio Paint: base, light guide, shadow, overlay, and highlights.

Let’s quickly get into it!

Base Color

Start by choosing a base color for your skin.

Usually I go with the upper left part of the color wheel, with desaturated warm tones

If you have a clean lineart you can use the Selection Fill tool (link below) to color the base quickly

If you crossed a line use the Erase Along Edge eraser to quickly erase the overflow

Light Source

On a new layer, draw a small sun around where you want your lights to come from. Guidance only — a really simple sun is enough.

Now, following that sun, draw lines toward your art to see where the light would fall.

Try to think of the shapes in 3D to guide your light.

This will help you know where to place light and shadows for the next steps.

Shading

Select a desaturated dark color with a hue opposite to what you picked for the skin color.

Use the Lasso tool to select areas opposite to the light source, following the 3D shapes from before.

On a new Multiply layer clipped to the skin layer,

paint the color in with a pen brush. I usually use the Mili pen with a large size to fill it in.

Choose a blending brush and use it on the edges. Smudge and push the colors toward the other direction.

Then create a new multiply layer on top and add in the darker shadows, you can use the same color or change hue for variation

This step you can follow your art style and blend to your liking. Stop when you like the result — don't overdo it.

Overlay

Select a bright color for your transition color.

On a new layer, use an Airbrush to lightly brush the color along the shadow edges.

Set the layer's mode to Overlay so the color is not too strong.

This is what it looks like on a normal layer

You can use multiple colors and experiment with different saturations. Usually, I use a redish color to give the skin a lively vibe.

Here’s the difference between overlay layer and a normal layer

Highlights

Select a slightly saturated color for your highlight. You can test different colors.

Using the Lasso tool, select the highlight areas following the light source.

On a new layer, clipped to the skin layer, paint in the highlight color.

Blen it slightly so not all edges are sharp

Try out different blending modes for the highlights. Usually I stick with Screen mode, but soft light and other light modes may be interesting (Overlay also gives a warm feel)

here’s what screen looks like vs overlay

Now select a color close to white

and, on a new glow dodge layer, draw thin lines and dots on the areas where light is concentrated and highlights appear

And that's it! You effectively and quickly have lively skin =D

5 points to remember

1. Warm desaturated base — upper-left of the wheel.

2. Light guide sun + 3D shapes before you shadow.

3. Shadow = opposite hue, Multiply, then blend.

4. Overlay airbrush on edges for lively transition.

5. Screen highlights + tiny white dots for life.
