Load up your iPhoto Library and then head to the top menu and click on iPhoto. Now click on the Preferences option to see the Preferences window spring to life.
Now click on the second tab along the top bar of iPhoto’s Preferences called Appearance. Here you can access all of the options to alter the way the iPhoto user interface works and looks.
Use the Background slider in the middle of the Appearance window to change the colour from Black to White. The slider naturally allows for all the grey colours in between the two options.
Use the tick boxes to make other changes to the interface. You can even change the size of the sidebar text by using the Source Text drop-down menu at the bottom of the window.
