When creating a (bar) plot in pgfplots, tex uses a default list of colors. What are the definitions of these colors?

There are a couple of issues here: cycle list name is the right way to approach this, and the cycle list will be respected as long as you use \addplot +[...]. However, you need to use cycle list name after ybar, since ybar sets its own list.
Furthermore, you need to make sure to either put a % after the last entry in the cycle list, or to put the closing } directly behind it (not on a new line).
To get black labels, add black to the every node near coord style.
To align the bars with the tick marks, set ybar=0pt, bar shift=0pt.

The OPs code gives the expected result (from the point of view from PGFPlots), but I think "the user" expects that "the last shown color" in the colorbar should be the last defined color in the colormap.
With OPs code that "last color" is indeed used in the colorbar, but only at 1 (and above), so it is invisible. Luckily with PGFPlots v1.14 there where introduced many new features regarding colormaps and colorbars so it is now very easy to create the colorbar "the user expects".
For more details please have a look at the comments in the code.
