There's an example in the Wiki
<https://github.com/weewx/weewx/wiki/Colored%20UV%20index> of how to do
this, but I don't think it's particularly efficient.
A search list extension would probably be the most elegant. Then you could
do something like:
<tr>
<td class="stats_label">UV</td>
<td class="stats_data" style="background-color:
$UV_color($current.UV.raw)">$current.UV $UV_text($current.UV.raw)</td>
</tr>
The functions $UV_color() and $UV_text() would return an appropriate color
and warning, respectively, depending on their argument. An elegant touch
would be for $UV_text() to get its strings out of skin.conf, making it easy
to internationalize the text.
