Overview
Introduction
This tool takes a list of integers and renders each one as its own colored line, cycling through a fixed palette by position so every entry is easy to tell apart at a glance.
It's purely a visual aid: the coloring carries no meaning about the value itself, only about where it sits in the list.
What Is Integer Colorizer?
A list colorizer for integers, one value per line, where each line is assigned a color from a fixed rotating palette based purely on its position.
The palette has 8 distinct colors and wraps back to the start after the eighth entry, so a 20-line list repeats the same 8-color cycle two and a half times.
How Integer Colorizer Works
The list is parsed and validated first; every non-blank line must be a plain integer, or the tool reports which line failed.
Each validated value is paired with a color index equal to its position in the list (0, 1, 2, ...), and the component looks up that index's color from the shared rotating palette, wrapping with a modulo once the palette's 8 colors are exhausted.
The unmodified list is also returned separately as plain text, for a quick copy without the color styling.
When To Use Integer Colorizer
Use it to visually distinguish entries in a moderate-length list of integers, such as IDs, indices, or generated values, at a glance.
It's also handy for a quick presentation or screenshot where color makes a list of numbers easier to scan than a plain monochrome block.
Often used alongside Integer Digit Colorizer, Integer Digit Highlighter and Integer Highlighter.
Features
Advantages
- Zero configuration: every list is colorized automatically with no options to set.
- Deterministic: the same list always gets the exact same coloring, since color only depends on position.
- Reuses the site's existing shared color palette, so it looks visually consistent with the hex category's colorizer tools.
Limitations
- Purely decorative; the coloring carries no data meaning and shouldn't be relied on to convey anything about the integer's value or sign.
- With more than 8 entries, colors repeat, so position beyond the 8th entry is only distinguishable by the label/value itself, not a unique color.
- Requires a rendering context that supports inline color styling; the plain-text copy output has no color information.
Examples
Best Practices & Notes
Best Practices
- Keep lists to 8 or fewer entries if you want every line to have a visually unique color.
- Use the plain-text copy output, not the colored rendering, when you need to paste the list somewhere that doesn't support styled text.
Developer Notes
The lib returns a `segments: {text, colorIndex}[]` array (colorIndex equal to each line's position) and leaves the actual color lookup to the component via the shared `paletteColorAt` helper from the hex category's color-shared module, keeping the palette itself defined in exactly one place across categories.
Integer Colorizer Use Cases
- Visually distinguishing entries in a list of IDs or generated values
- Making a list of numbers easier to scan in a screenshot or presentation
- Quickly spotting a specific line's position by its consistent color across repeated views
Common Mistakes
- Expecting the color to indicate something about the value (like sign or magnitude); it's assigned purely by list position.
- Assuming every entry in a long list has a unique color; the 8-color palette repeats every 8 entries.
- Pasting the colored rendering somewhere that strips styling and expecting the colors to persist; use the plain-text copy output for that instead.
Tips
- Reorder your input list and re-run the tool to see how the coloring shifts with position, not value.
- Pair this with the Integer Duplicator or a generator tool to visually track duplicated or generated entries.
