Looking at any integration output logs will show that with NO_COLOR=1 set in the environment, the regular logs are uncolorized but the ones that make up the assessment log are wrapped in ANSI escape sequences for color.

Looking at the code, the reason is the logs use a boolean to turn colors off while the report uses a boolean to turn colors on.  Switch the report to use a boolean to turn colors off so it agrees with what already exists in logging.
