Start with the face. On almost every scientist page, the face is the smallest but most important area, so apply color first with light, even strokes. Use a flesh tone that matches the character, then add a soft shadow under the chin, the nose, and the brow with a slightly deeper shade. If you do the face first, you can build the rest of the artwork around it and avoid smudging a finished lab coat while you work.
Quick tool and color guide for scientist pages
| Element | Best tool | Best colors | Notes |
|---|---|---|---|
| Lab coat | Colored pencils | White, light gray, pale blue | Leave the white paper as highlight; add gray only in folds |
| Skin | Colored pencils | Warm peach, tan, deep brown | Layer twice for smoothness |
| Hair | Colored pencils or markers | Gray, white, brown, black | Use short strokes for texture |
| Glasses | Markers or gel pens | Black, silver, dark blue | Add a white dot for shine |
| Spacesuit (astronaut) | Markers | White, silver, red, blue | Keep the suit mostly white; use color only for accents |
| Background (lab, space, plants) | Crayons or markers | Soft blues, greens, purples | Keep background lighter than the subject |
Match the tool to the detail
Scientist pages mix large areas (lab coats, spacesuits, chalkboards) with tiny details (glasses, test tubes, buttons, beakers). That mix calls for different tools depending on what you are working on.
Use colored pencils for anything that needs control: faces, hands, small equipment, and text on a chalkboard. Pencils let you layer and shade without going over the lines. For large areas like a lab coat or a spacesuit, switch to markers if you want flat, bold color, but be careful—markers bleed through thin paper, so place a scrap sheet underneath. Crayons work well for backgrounds and for young colorists, but they make precise details harder. If you are using crayons, do the small parts first with a sharp tip, then fill the big areas.
If you are unsure which medium suits you, read how to choose colors that look good on coloring pages before you start.
Get the lab coat right
The lab coat is the most iconic part of many scientist pages. It is also where most people go wrong by making it solid white or solid gray. Instead, leave the white of the paper for the highlights and use a light gray or pale blue pencil to add shadows in the folds—under the collar, inside the sleeves, and along the sides.
Work in small circular strokes, then blend with a tissue or your finger. For a smoother gradient, read how to blend colored pencils on coloring pages. If the page has a pocket or buttons, color those with a darker gray or silver to give the coat structure.
Make the spacesuit look metallic
For astronaut pages, resist the urge to color the whole suit gray. That makes it look flat. Instead, use white for most of the suit, then add silver or light gray shading on the side opposite the light source. Add small colored accents—red, blue, or orange—on the chest panel, the sleeves, and the helmet rim. Those small pops of color make the suit read as “space gear” instead of “white pajamas.”
For the helmet visor, use a dark blue or black marker, then add a small white crescent or dot for a reflection. That single highlight sells the glass effect. For more shading techniques, see how to shade coloring pages for more depth.
Step-by-step: Coloring a classic Einstein page
Try this on an Albert Einstein coloring page with a chalkboard or lab bench background.
1. Color the face and hair first
Use a light flesh tone for the face. Then use white or light gray for the hair and mustache, but leave the paper white where the light hits the top of the head. Add a few darker gray strokes at the roots and under the mustache for volume.
2. Add the glasses and eyes
Color the frames dark brown or black. Leave a tiny white dot in each lens. Fill the eyes with dark brown or black, then add a small white reflection.
3. Shade the lab coat
Use a light gray pencil to shade the folds of the lab coat. Keep the front of the coat white. If the page has a tie, color it dark red or blue for contrast.
4. Do the chalkboard or background
Color the chalkboard dark green or dark gray. Use a white or yellow pencil to write a formula or draw a simple atom. If the background is a lab bench, use brown or gray for the wood and metal.
5. Finish with small details
Color the pocket pen, the buttons, and any test tubes or beakers. Use a silver or gray pencil for metal tools, and add a tiny white highlight on glass items.
Which pages to start with
Start with a single character and a simple background. The Ada Twist coloring pages are ideal because they have clear outlines, large areas, and a fun mix of lab gear and casual clothes. Ada’s glasses and braids give you practice with details without being overwhelming.
If you prefer a classic portrait, go to an Albert Einstein coloring page. His wild hair and mustache are forgiving—you can use loose strokes and it still looks intentional. Avoid the most detailed pages (like ones with multiple scientists or complex space scenes) until you feel comfortable shading and blending.

Who should do it differently
If you are a beginner, skip the markers on your first scientist page. Markers are unforgiving—you cannot lighten a dark patch. Use colored pencils and focus on shading the lab coat and the face. If you are a parent coloring with a young child, let them choose the colors freely, even if the scientist ends up with a purple lab coat. The goal is fun, not realism.
If you are an experienced colorist, challenge yourself by adding a light source. Pick one direction for the light and keep all shadows on the opposite side. Use a white gel pen for highlights on glass and metal. That level of control will make your scientist pages look dimensional. For more on matching tools to the job, check colored pencils, markers, or crayons for coloring pages.
And if you are coloring an astronaut, remember that the same rules apply: white base, gray shadows, and a single bright accent. The astronaut coloring pages guide goes deeper into that specific subject, just as the doctor and engineer guides cover their own details. The same logic works across all profession pages: start light, shade in layers, and keep the face the focal point.
Above all, keep the paper clean. Rest your hand on a spare sheet, and you will avoid smudging the white lab coat you worked hard to keep bright.
