### Special "primitives" (not really primitives but they exist solely for coloring)

| primitive                   | default color              | configurable |
| --------------------------- | -------------------------- | ------------ |
| `leading_trailing_space_bg` | Color::Rgb(128, 128, 128)) | \*           |
| `header`                    | Color::Green.bold()        | \*           |
| `empty`                     | Color::Blue.normal()       | \*           |
| `row_index`                 | Color::Green.bold()        | \*           |
| `hints`                     | Color::DarkGray.normal()   | \*           |

Here's a small example of changing some of these values.

```nu
let config = {
    color_config: {
        separator: purple
        leading_trailing_space_bg: "#ffffff"
        header: gb
        date: wd
        filesize: c
        row_index: cb
        bool: red
        int: green
        duration: blue_bold
        range: purple
        float: red
        string: white
        nothing: red
        binary: red
        cellpath: cyan
        hints: dark_gray
    }
}
```

Here's another small example using multiple color syntaxes with some comments.

```nu
let config = {
    color_config: {
        separator: "#88b719" # this sets only the foreground color like PR #486
        leading_trailing_space_bg: white # this sets only the foreground color in the original style
        header: { # this is like PR #489
            fg: "#B01455", # note, quotes are required on the values with hex colors
            bg: "#ffb900", # note, commas are not required, it could also be all on one line
            attr: bli # note, there are no quotes around this value. it works with or without quotes
        }
        date: "#75507B"
        filesize: "#729fcf"
        row_index: {
            # note, that this is another way to set only the foreground, no need to specify bg and attr
            fg: "#e50914"
        }
    }
}
```

## Shape Values

As mentioned above, `shape` is a term used to indicate the syntax coloring.

Here's the current list of flat shapes.

| shape                        | default style                          | configurable |

| `shape_bool`                 | fg(Color::LightCyan)                   | \*           |
| `shape_custom`               | bold()                                 | \*           |

| `shape_nothing`              | fg(Color::LightCyan)                   | \*           |
