Pick a color and a shape to see how many example pills would still fit. It's a quick way to learn why those two clues alone can't name a pill.

Illustrative only: these are invented proportions, not a real database. They exist to show why color and shape alone rarely reach a single answer, whatever the actual combination.
1. Pick a color
2. Pick a shape
Pick a color and a shape above to see roughly how many illustrative candidates are still left.
This tool never identifies a real pill. It only illustrates why two attributes are rarely enough, so the next step (imprint, photo, pharmacist) makes sense.
How to use it
- Pick the color that's closest to your pill from the first row.
- Pick its shape from the second row.
- Read the box below. It shows roughly how many of 1,000 example pills would still match.
Try a few combinations. Even an uncommon pairing leaves several candidates, and a common one like white and round leaves a lot.
What your result means
The count is a teaching example. The proportions are invented, so it isn't a search of real medicines and it can't tell you what your pill is. What it shows is the principle: each clue removes only some candidates, and color and shape together still leave many.
That's by design. The imprint code, combined with size, shape and color, is what regulators rely on to make a product identifiable. Color and shape rule options out, but they don't pick one.
What to add after color and shape
- The size, measured across the widest part.
- Any score line, coating or markings, even faint ones.
- Imprint characters on either side, including partial ones.
- The pill's source: which bottle, drawer or bag it came from.
If you have an imprint, a lookup in a resource such as the National Library of Medicine's DailyMed can help you check a lead. Our guide to identifying a pill by color and shape covers the next steps. Don't take a pill you haven't positively identified, and treat a pharmacist as the final word. If a child or pet may have swallowed an unknown pill, call Poison Control at 1-800-222-1222.
Frequently asked questions
Can I identify a pill by color and shape alone?
Not with confidence. Federal rules treat the imprint code, together with size, shape and color, as what makes a product identifiable. Unrelated drugs can share the same color and shape.
Are the numbers in this tool real?
No. The proportions are invented for teaching, and the starting pool of 1,000 is an example, not a real product count. The tool shows the idea, not a real database search.
Why are so many pills white and round?
Round white tablets are simple and cheap to make, so many unrelated products end up looking alike. Nothing in U.S. drug law requires color or shape to be unique.
What should I add after color and shape?
Anything else you can see: the exact shade, the size, a score line, the coating, and any imprint characters, even partial ones. Then confirm with a pharmacist.
What if I found a pill and don't know what it is?
Don't take it. Keep it away from children and pets, and ask a pharmacist. If anyone may have swallowed it, call Poison Control at 1-800-222-1222.
