I'm doing a theme in tumblr and wanted to change the color of the labels in the chat, so that in each line they alternated colors. It turns out that they all have the color set in odd
.label:nth-child(odd){color: #012E5E; font-style: italic;}
.label:nth-child(even){color: #D8A307; font-style: italic;}
This is the chat block
{block:Chat}
{block:Lines}
{block:Label}<span class="label">{Label}</span>{/block:Label} {Line}<br/>
{/block:Lines}
{/block:Chat}
And it stays that way
