A homemade numbered page is a great gift, a classroom tool or a rainy-day project. DIY color by numbers needs only a drawing, a few numbers and a key, and you can make one in under an hour. This guide covers the by-hand method, a way to build math versions, and how to make a custom page from a photo.
What you need for DIY color by numbers
For the by-hand method you need plain paper, a black pen, a pencil and eraser, a ruler, and the pencils or crayons you plan to color with. A light box or a bright window helps if you want to trace a design. You do not need to draw well. Simple shapes work best.
Step 1: Draw a simple picture with closed shapes
Start with a subject that breaks naturally into big areas: a fish, a house, a flower, a balloon bunch, a sailboat. Draw bold outlines and make sure every shape is closed, meaning there are no gaps where color could leak into the next area. Keep the areas large enough to hold a number. A good rule is that each area should be at least as wide as a fingertip.
Skip fussy detail on a first try. A picture with 20 to 40 areas is plenty.
Step 2: Choose the colors
Pick a small set. Six colors make an easy page, and ten make a medium one. More than that, and the page becomes a project. For a young child, choose colors that look clearly different from each other, such as red, blue, yellow, green and orange, rather than three shades of blue.
Decide which color goes in each area and write the plan lightly in pencil in each shape. Keep the same color for the same kind of thing: all the leaves green, all the petals pink. Repeating colors makes the page feel organized and helps the finished picture look right.
Step 3: Number the areas
Give each color a number. The lightest color is often 1, but any order works. Write the number in each area in small, neat digits. Pencil first, then trace over with a pen when you are sure. If two touching areas share a color, you can merge them by erasing the line between, or leave the line and use the same number on both sides.
Make the numbers small and light. They should be readable, but not so heavy that they show through the color.
Step 4: Make the key
Make a small box in a corner of the page, or on a second sheet. List each number, write the color name beside it, and color a swatch of that color. Writing the name matters because it lets someone use any brand of pencils, and it makes the page readable in black and white.
Step 5: Test it
Ask a friend or a child to color the page. Watch for areas that are too small, unclear numbers and colors that look too similar. Fix those on the original and then copy or print the final version.
A math version
To turn your page into math practice, replace each number with a problem and list answers in the key. For multiplication, an area might hold 6 × 7, and the key would say 42 is blue. For addition, an area might hold 8 + 5, and the key would say 13 is green. A few rules keep it fair:
- Each answer gets exactly one color.
- Check every problem and its answer before you copy the page.
- Different problems with the same answer share a color, such as 3 × 4 = 12 and 6 × 2 = 12.
- Keep the answers few, so the key does not get long.

Make a custom page from a photo
If you want a numbered page of a real place, a pet or a person, do it digitally. The Custom Paint by Number tool turns a photo into a numbered pattern with a color key. You choose 12, 24 or 36 colors and the level of detail, preview the result for free, and download a PDF. Photos with a clear subject and good light give the cleanest areas. Because it works from a photograph, the result is a paint-by-number style pattern, which is detailed and best for older kids and adults.
For a simpler, thick-lined page that you color without numbers, try the Photo to Coloring Page tool, or read how to turn a picture into a coloring page.
Tips for better homemade pages
- Use black pen, not pencil, for the final outlines.
- Draw on thick paper or print on 28 to 32 lb stock so pencils can layer.
- Leave a margin, because printers cut off the edges.
- Put your name or a date in the corner for gifts.
- Make several versions at different difficulty levels for a mixed class.

FAQ
Can I make a color by number without drawing skills?
Yes. Trace a simple shape, use a printed outline from a coloring page, or start from a photo. Numbers and a key are all you need to add.
How many colors should a homemade page use?
Five or six for young kids, seven to ten for school-age kids, and a dozen or more for adults. Fewer colors make a page easier and faster.
Is there a color by number generator?
Yes, for photos. The Custom Paint by Number tool generates a numbered pattern and key from a picture you upload.
Can I sell my own color by number pages?
You can sell pages you drew yourself. Do not use characters, logos or other artwork that belongs to someone else. Read how to sell coloring pages for the basics.
