+====================================================
+
+preview-latex tries to adjust the foreground and background colors of
+generated images to those of Emacs.  Unfortunately, incompatible changes
+introduced in Ghostscript 9.27 breaks the traditional method partially,
+and preview-latex can display no images under certain circumstances.
+
+   A new method implemented alternatively works only with Ghostscript >
+9.27.  If you are using Ghostscript 9.27 or earlier, customize the
+option 'preview-pdf-adjust-color-method'.
+
+ -- User Option: preview-pdf-adjust-color-method
+     Method to adjust colors of images generated from PDF.  It is not
+     consulted when the LaTeX command produces DVI files.
+
+     When the option is 't' (default), preview-latex adjusts the FG and
+     BG colors of the generated images by the new method.  This method
+     requires that Ghostscript has working 'DELAYBIND' feature, thus is
+     invalid with gs 9.27 (and possibly < 9.27).
+
+     When it is 'compatible', preview-latex uses traditional method.
+     This option is provided for backward compatibility with older gs.
+     See the below explanation for detail.
+
+     When 'nil', no adjustment is done and "black on white" image is
+     generated regardless of Emacs color.  This is provided for fallback
+     for gs 9.27 users with customized foreground color.  See the below
+     explanation for detail.
+
+     When the LaTeX command produces PDF rather than DVI and Emacs has
+     non-trivial foreground color, the traditional method ('compatible')
+     makes gs >= 9.27 to stop with error.  Here, "non-trivial foreground
+     color" includes customized themes.
+
+     If you use such non-trivial foreground color and the version of
+     Ghostscript equals to 9.27, you have two options:
+       1. Choose the value 'compatible' and customize
+          'preview-reference-face' to have default (black) foreground
+          color.  This makes the generated image almost non-readable on
+          dark background, so the next option would be your only choice
+          in that case.
+       2. Choose the value 'nil', which forces plain "black on white"
+          appearance for the generated image.  You can at least read
+          what are written in the image although they may not match with
+          your Emacs color well.
+
+     The default value used to be 'compatible' for short period before
+     Ghostscript 9.50 was released but now is 't'.
