Change the color of Active Child Boards?

[Saint_3k]

I want to change the color of the active child boards displayed on the main page of my forum, so that they stand out from the inactive ones better.

Does anyone know the code I need to change to be able to do that? I looked through Boardindex.php and found a couple of lines that might be the ones I'm looking to change, but I was unable to produce the desired effect.

I'm running SMF 1.0.4

Here is a demonstration of what I want it to do (Photoshoped)

what makes a child board active?

Mouseover I guess?

Open: BoardIndex.template.php
Find: $children[] = $child['new'] ? '<b>' . $child['link'] . '</b>' : $child['link'];
Replace with: $children[] = $child['new'] ? '<span style="color: #FF0000;">' . $child['link'] . '</span>' : $child['link'];

(I think)
