If you too hate those wooden colors in the contacts, here is a little mod which ‘removes’ them. To do this mod, first backup your existing contacts.apk and chose either of the following options (whichever is applicable for your Tab)
US Galaxy Tab:
First, backup your existing Contacts.apk and Contacts.odex to somewhere else then remove them and replace with the Contacts.apk from here. Do a reboot after that.
European Galaxy Tab:
Replace contacts.apk with root explorer (overwrite) and restart Tab. Get the modded apk from here
