The back of the 'neck' was white on the refit, but was painted pale blue on the A. The paint scheme was also 'supposedly' changed after TMP. The original pearlescent paint scheme would not have worked with the blue screen effects ILM were going to use in WOK, so it was re-painted a dull grey. The TMP version is still my favorite ship design of all time.
