In XCode 4.2, I want to set a view’s background colour to a particular RGB value. However, I don’t appear to have the “RGB Sliders” option that I used to have (perhaps in a previous version). I’m looking for something like the dialog shown in this answer to another question, but all I’ve got is this:

There are no other options in the drop-down that says “Spectrum”. Does anyone know if/how I can get XCode to accept RGB or hex values?
I figured it out:
Click on the button on the top right of the title bar to reveal the toolbar.
Click on the sliders icon.
Seems obvious in hindsight, but if you don’t know then you don’t know.
