That reminds me of the early days of Star Trek and when they first introduced the Orion slave girls. The actresses were painted a deep green but when the directors viewed the rushes, the colour of the Orions was all washed out. They increased the colour intensity by using brighter skin paint but time and time again when the rushes were viewed, the green skin colour of the Orion slave girls would be washed out.
Finally in frustration, the director asked the film processors if there was anything strange about the film being used. At first he said no but then remarked that they had been having trouble with some of the colours: these dancing girls kept on coming up with a dark green skin colour and they were having a terrible time trying to get rid of the green!
