The `$select` *widget* supports use of a `class="..."` attribute, but NOT `
style="..."`.
In order to change the color of the `$select` widget, you will need to
define a CSS classname that specifies the background color.
Something like this:
```
<style>.thisColor { background:{{!!color}}; }</style>
<$select field="color" class="thisColor">
<$list filter="[enlist<X11Colors>]" variable=thisColor>
<option style={{{ [[background:]] [<thisColor>] [[;]] +[join[]]
}}}><<thisColor>></option>
</$list>
</$select>
```
