Reminders app theme!

So I'm sure we are all aware of the gnarly leather and red combo thats is the Reminders app in Mavericks and Ive been dabbling with the resource files to try and spice it up a tad (might be futile but we will see!)

so far I've just modded the highlighted category and made it blue..but I'm hoping to remove the red text. Anyone know where I could possibly change the colour value?

i won't go to crazy..but it would be nice to scrap the leather (keep it black)..and swap the red for blue etc
