I want to assign seperate colors to each `<td>`. One solution is to use classes, but I don't want to crowd the HTML if a simple CSS selector solution exists. 

HTML:

```
<tr>
  <td>Item 1</td>
  <td>Item 2</td>
  <td>Item 3</td>
  <td>Item 4</td>
</tr>

```

CSS: 

```
/* item #1 */
{color: red}

/* item #2 */
{color: blue}

/* item #3 */
{color: green}

```
