So you are telling me that loads of pink and magenta flashes and stuff are intentional?
Yes, there absolutely are pink/magenta flashes during laser blasts etc. on all surviving prints, and it was that way when I screened it many, many times back in 1977 and again in 1980 and again in 1982.
That is how it always was in the cinema. Most people wouldn’t notice it as it is one or two frames, i.e. often just 1/24th of a second, but it is how it was.
Anyone is free to re-colour the films to a version they prefer of course, but if you are interested in how it was in cinemas at the time, the blasts did have magenta flashes in many of the ‘explosions’.
