I was able to follow the whole tutorial in one evening (not without some difficulty).
Everything in the design environment (IDE) looked the same in the video (or close enough) with exception of the pick-color dialog. My dialog was completely blank (no predefined colors). Did I do anything "wrong?"
Note: I am using version 13.1 of Dreamweaver (current as of November 2013) and "asset" files downloaded from the Web site.
The videos were recorded using the original version of Dreamweaver CC, which had a different colour picker. The colour picker was updated in Dreamweaver 13.1, which was released in August 2013.
