Every time I try and change the color of the header in the daily view (located in templates/extcal_daily_view.htm)I mess up the header. The default is a red #FF3333. All I do is change the hex value of the color and it screws up the header and shows the code in the header.

Like so: style="background-color: #CC3333;">

The only thing I did was change the numbers. Does anyone know what gives with this? Can you only use that red color?

Here's a strange thing that I noticed. I compared the file that I modified with the original file in the xtCal folder by opening up both html files in my browser. When I did I noticed a discrepancy, wherein the file I modified listed this bit of code:
<{if $dayevents[i].id == $id}> style="background-color: #CC3333;"<{/if}>><{$dayevents[i].title}>

In the original file that line looks like this:
style="background-color: #ff3333;"<{/if}>><{$dayevents[i].title}>

There's no <{if $dayevents[i].id == $id}> line. But all I did was change the #ff3333, why does this cause the mix up?
