Color

All pixels specified by <Color> are given the value of <NewColor>.

The colour transformation takes place in a display buffer that has the same properties as the screen on which the screensaver runs.  If the screen colour depth is set to a low level (4, 8 or 16 bit mode) many pictures in the screensaver will appear quite different than at higher colour depth setting.  Because of this, it is sensible to substitute old (unsupported) colours - use rather the coordinate form of the <Color> parameter instead.  The parameter lists can consist of multiple <Color>, <NewColor> - pairs inside a single [C: ] command.
