How to Use Colorized List Item Online Free Tool

  1. Paste your list into the input - one item per line. Blank lines are filtered out automatically.
  2. Pick a colour scheme from the eight built-ins. Rainbow and Vibrant are high-contrast; Pastel and Ocean are softer; Monochrome is neutral.
  3. Choose an assignment mode: cycle through the scheme (default), independent random colour per item, or a zebra alternation between two scheme colours.
  4. Select an output format: HTML with inline styles (drop-in ready), HTML + CSS classes (easier to theme later), or a full HTML page you can download and open directly.
  5. Press Ctrl+Enter (⌘+Enter on Mac) or the Generate button to render the preview and fill the output code box.
  6. Copy or Download: the preview uses contrast-correct text colour (white on dark swatches, black on light) so the result is readable without extra work.
  7. Clear resets every field and the preview back to the initial state.

Frequently asked questions

How do I add colours to list items?

Paste your list (one item per line), pick a scheme and an assignment mode, then press Generate (or Ctrl+Enter). The preview and the output code update together.

What colour schemes are available?

Eight: Rainbow, Pastel, Neon, Monochrome, Earth, Vibrant, Ocean, and Sunset. Each has nine ordered colours; longer lists cycle through.

What are the three assignment modes?

Cycle through scheme uses the scheme’s colours in order and wraps. Random generates a fresh random hex per item (fun for brainstorm lists). Alternating uses the first two scheme colours as a zebra pattern – handy for table-like lists.

What output formats are supported?

HTML inline styles (easy to paste into any editor), HTML + CSS classes (separates concerns for easier theming later), and a full HTML page (complete with doctype and a background colour, ready to download).

Can I download the coloured list as a file?

Yes. HTML inline and full-page modes download as .html, which opens directly in any browser. The HTML+CSS mode downloads as .txt since it contains both blocks separated by a comment.

Is my list data private?

Yes. Everything – splitting, escaping, colouring, rendering – happens in your browser. The tool works entirely offline once loaded; no network requests of any kind.

Can I pick a custom colour for each item?

Not in-tool yet – the schemes and modes cover most cases. For bespoke palettes, generate the HTML+CSS output and edit the class colours in the CSS block. That way the list structure stays intact and you only touch the colours you care about.

Is the text colour readable on every background?

Yes. The tool picks a contrast-correct text colour per item – dark text (#0f172a) on pale backgrounds and white text on dark ones, based on the W3C relative-luminance formula.

Does it escape HTML inside my items?

Yes. Angle brackets, ampersands, and quotes are escaped with a pure function, so you can include items like <button>Click</button> verbatim without breaking the output.

How many items can it colour?

No hard limit – the tool renders thousands of items in well under 30 ms. Colours cycle through the scheme, so item 10 shares its background with item 1 when a 9-colour scheme is selected.
