George and Harold can turn an ordinary school day into something the principal would strongly prefer had never happened. Their homemade comic-book enthusiasm is part of the charm of Captain Underpants. The grand superhero attitude becomes especially entertaining when the costume looks as though it was assembled in a considerable hurry.
Captain Underpants coloring pages fit that pleasure in making something funny with paper and imagination. A child may pause to recall a favorite joke, then decide the explanation requires a sound effect. The finished picture can sit beside a comic of their own, where the next unlikely superhero is already waiting for a name.

Coloring Ideas for Captain Underpants Pages
Try one of these coloring ideas, or use them as a starting point for your own.
Give the Cat a Familiar Coat
The cat held overhead beneath the tree gets a fine entrance, with smiling faces and raised arms below. Its striped fur is a good place to bring a familiar animal into the scene. You could borrow the colors of a cat you know, or choose the coat you would give an entirely imaginary one.
Work with the stripes already drawn, carrying your chosen fur color into the spaces around them. If your inspiration is a gray cat, a ginger one, or a mixture, adapt those colors to this cat’s markings. Keep the nearby clouds white and choose a quieter shade for the tree trunk, leaving that small, lifted animal easy to spot.
Decide What the Laboratory Machine Does
A wheeled machine with a gauge, knobs, a lever, and a flexible instrument arm practically invites a little speculation. Before coloring it, decide on one wonderfully unnecessary job: perhaps it sorts biscuits by crunch or measures how loudly someone can whisper. The two scientists can look perfectly serious about either possibility.
Let that invented purpose guide the controls. A biscuit sorter might have a golden knob for gentle handling and a red one for an emergency stop. Choose where the gauge would signal that everything is going well, then color that part distinctly. Carry one machine color onto the small lamp, and leave the lever ready for the scientist holding it.
Switch on the City Below
Captain Underpants is airborne and waving above rooftops, chimneys, and a water tower. Try setting his flight at the hour when windows begin to glow but the shapes of buildings are still easy to see. The repeated windows give you somewhere specific to put that evening light.
Choose a dusky blue or violet for the sky, then make a few windows warm yellow. Others can stay dark; every building needn’t have all its lights on. Use deeper shades around the lit windows and keep the rooftop structures clearly separated from the sky. Finish with a brighter cape above the quieter streets, as though the evening still has one conspicuous visitor.
Borrow a Corner of the Drawing Room
Two children draw at a wooden table, surrounded by pinned pictures, pencil containers, and a lamp. One holds up an illustrated sheet. It feels like the appealing middle of making something, when the table is busy and there is already a picture worth showing.
Color the room as a place you would like to spend an afternoon. Give the lamp and supply containers colors you would happily have on your own table, and let the wooden walls stay relatively quiet around the little artworks. Then borrow one manageable detail for your actual coloring spot: gather loose supplies into a cup, clear a place for the current page, or put a finished drawing where you can see it.
Give the Flying Cape a Proper Trim
Above the school, the large flying character’s cape has stitched trim. That small clothing detail deserves a turn in the spotlight. Think of the edging on a favorite blanket or jacket: a narrow border can be the part that makes the whole thing recognizable.
Choose the trim color first, then pick the main cape color beside it. A yellow edge around blue could look cheerful, while a dark border could give a pale cape a stronger outline. Follow the trim around its bends, keeping the stitching marks visible. Echo that edging color in the school flag below, then color the building in quieter shades so the two pieces of fabric catch the eye.
Decorate the Most Unreasonable Bathroom
Three toilets have arms and expressions, while the central character holds two plungers. The bathroom has already abandoned ordinary behavior, so you can be surprisingly sensible about decorating it. Pick a room color you might actually enjoy around the two sinks and rectangular mirrors.
Use the wall tiles to establish that color, then add a single contrasting row across the tiled wall, following the existing divisions. Keep the floor simpler so the room doesn’t compete with every face. You might leave the fixtures mostly white, with small touches of cool gray, as if this were a perfectly respectable bathroom. Finish by giving the two plungers matching handles, neatly coordinated amid the commotion.
Put Yourself at the Robot Controls
The smiling robot has a child in its open cockpit, two hand controls, and three panel buttons. Start with the cockpit and imagine settling into that seat. What would you want within reach if you were driving a machine with such a cheerful face?
Give each button a color for an invented function: one might start a slow walk, another make the robot wave, and the last sound a ridiculously polite horn. Use those choices to guide a few details on the robot, such as carrying the waving button’s color onto an arm segment. Color the seat in your own favorite shade. Once the page is finished, tap a pictured button and supply the horn yourself.
Set Out a Small Welcome-Home Celebration
Raised fists, wide smiles, stars, and curled streamers make this scene a ready-made cheering crowd. It could become a welcome-home picture for someone returning from a trip, especially if your household’s usual greeting involves everyone talking at once.
Choose colors the returning person likes for the foreground clothing, then carry one of those shades into the streamers. Let the smaller background figures wear different colors so they feel like individual members of the gathering. Color the scattered stars last, giving them a bright finish against the white spaces. On arrival day, place the completed page on an entry table or beside their usual seat, where the whole little crowd will be waiting.
