How to use Color Integers
- 1. Paste the integers. Enter a list of integers separated by spaces, commas or newlines. Both positive and negative values, along with zero, are supported.
- 2. See each integer colored by sign. The tool colors negative integers red, positive integers green, and zero gray, so the overall balance of a list becomes visible at a glance rather than something you have to read carefully.
- 3. Review the colored output. Scan the rendered colors in the output panel to see the sign distribution across your list. Screenshot the panel if you need to share the visual with someone else.
When to use Color Integers
Color Integers renders a list of whole numbers with color coding by sign, red for negative, green for positive and gray for zero. Color Integers turns a column of mixed-sign values into something you can read visually rather than number by number.
- Reviewing a list of profit and loss figures. A quarterly report lists gains and losses as plain integers like -3 0 7 -12 5. Coloring them by sign makes the overall trend visible instantly, without scanning for minus signs.
- Presenting balance changes in a talk or demo. Explaining how a running total moves up and down is clearer when the audience can see red and green values rather than reading a plain list of numbers.
- Spotting an unexpected zero in a dataset. A batch of transaction amounts should never include a zero value if the data pipeline is working correctly. Coloring the list makes a stray zero stand out in gray immediately.
- Reviewing test output with mixed deltas. A test suite reports numeric differences between expected and actual values. Coloring the deltas by sign highlights which cases came in too low or too high at a glance.

About the Color Integers tool
Color Integers runs as plain JavaScript in your browser tab, with no server behind it. Color each integer by its sign: negative, positive or zero. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Integer Tools section, 133 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Color Integers cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
Can I save what the tool produces?
Yes. Use the download or copy controls in the output panel to keep the rendered result once it looks the way you want.
