"Large Type" background color

[benoitmars]

I'm wondering about the background color of the "Large type" action.
>From Quicksilver, this color is (sort of) dark purple, whereas from
the Apple's Address Book application, it's dark gray. I'd like to know
if there is a way to change the Quicksilver background color so as it
matches the one of the Address Book.

I've found this piece of code which looks related to this problem :

And the "QSAppearance1B" color is set in the QSDefault.plist file :

<key>QSAppearance1B</key>
<data>
        BAt0eXBlZHN0cmVhbYED6IQBQISEhAdOU0NvbG9yAISECE5TT2JqZWN0AIWEAWMBhARm
        ZmZmgz4HtDaDPcv0R4M+SlKUgz9MzM2G
</data>


 But I don't understand how to change this value… Can someone help me?
Thanks!
