# Highlight Range

> Set the background color of a Google Sheets range.

The **Highlight Range** action changes the background color of every cell in an
A1 range.

## Inputs

| Input                     | Type           | Required | Description                                       |
| ------------------------- | -------------- | -------- | ------------------------------------------------- |
| **Third-party account**   | Google account | Yes      | Account with write access.                        |
| **Spreadsheet ID or URL** | String         | Yes      | Spreadsheet to format.                            |
| **Range**                 | String         | Yes      | A1 range, such as `Sheet1!A1:B2`.                 |
| **Color**                 | Hex color      | No       | Six-digit `#RRGGBB` color. Defaults to `#FFD230`. |

When the range does not include a sheet name, the action formats the first
sheet in the spreadsheet.

<Note>
  This action changes only the cells' background color and returns no output. It
  does not alter values, fonts, borders, or number formats.

  <Accordion title="The color is rejected">
    Use a hash followed by exactly six hexadecimal digits, such as `#98FB98`.
    Three-digit shorthand and alpha-channel colors are not accepted.
