Hi @bakerpj. The color might give the impression that these messages are intended to communicate some sort of a problem has occurred, but it is not so in this case.
The developers of the 3rd party tool Arduino IDE uses for uploading made an unusual decision to print even the tool's purely informational output to the "standard error" stream (AKA "stderr") instead of the more common practice of printing it on the "standard output" (AKA "stdout") stream. Because it is usually associated with errors or warnings, Arduino IDE colors all output received from the stderr stream red (at least when the default IDE theme is selected).
So don't be mislead by the color of the text during the upload (though you should pay attention to red text printed while compiling because the color is significant in that case). As long as you don't see an "An error occurred while uploading the sketch" message on the notification bar of Arduino IDE, all is well with the upload.
