TW 7.7: Is the Scroll Bar Style limited to the five colors or can this be changed?

In TW 7.7 the Scroll Bar Style color selection seems to be limited to Black, Blue, Green, Orange and Red.  Is there a way to select other colors besides these basic five?  Thanks!

Dear customer, sorry for the late reply, you could add the scroll bar style with your custom ones, you will add them as in the sample folders below:
