the color reference in the wiki is only for the first stuff that shipped.
PLEASE DONT JUST USE THE COLORS, read the labeling to determine which line is which line.
all smart string nodes have positive, negative, and data.
what;s important is that the
positive matches up with the positive on the smart string controller
negative matches up with the negative on the smart string controller
data in matches up with the data on the smart string controller
what colors they use, or what colors you use does not matter, as long as the lines are connected as above.
EDIT: twooly, you are right go with the colors on the actualy smarts string nodes, and pay attention to the chip side as the input side. all other nodes, see above.
