+.SH DESCRIPTION
+.B blind-colour-matrix
+creates a colour conversion matrix, that is
+printed as blind video to stdout, for conversion
+from the colour space used by blind to a colour
+space with the primaries whose CIE XYZ values are
+.RI ( X1
+.I Y1
+.IR Z1 ),
+.RI ( X2
+.I Y2
+.IR Z2 ),
+and
+.RI ( X3
+.I Y3
+.IR Z3 )
+and whose white point is the colour whose
+CIE XYZ values are
+.RI ( white-X
+.I white-Y
+.IR white-Z ).
+If the white point is not specified,
+CIE Standard Illuminant D65 is used.

+.SH NOTES
+.B blind-colour-matrix
+may be changed in the future to use some other colour model,
+therefore, it is recommended to also use
+.BR blind-colour-ciexyz (1)
+if you are specifying the colour in CIE XYZ.

+.SH DESCRIPTION
+.B blind-primary-key
+reads a video from stdin and replaces a primary
+with transparency and prints the resulting video
+to stdout.
+.B blind-primary-key
+internally converts colour space to the one
+with the primaries whose CIE XYZ values are
+.RI ( X1
+.I Y1
+.IR Z1 ),
+.RI ( X2
+.I Y2
+.IR Z2 ),
+and
+.RI ( X3
+.I Y3
+.IR Z3 )
+and whose white point is the colour whose
+CIE XYZ values are
+.RI ( white-X
+.I white-Y
+.IR white-Z ),
+and replaces the first primary with transparency.
+If the white point is not specified,
+CIE Standard Illuminant D65 is used.
+.P
+If the colour space is specified, no conversion
+is done internally.
+.SH OPTIONS
+.TP
+.B -1
+Replace the the first primary with transparency. (Default.)
+.TP
+.B -2
+Replace the the second primary, instead
+of the first primary, with transparency.
+.TP
+.B -3
+Replace the the third primary, instead
+of the first primary, with transparency.
+.TP
+.B -g
+The video is, with the exception of the keyed primary,
+greyscale and the output video shall remain greyscale.
+.TP
+.B -z
+Parse arguments as CIE XYY instead of CIE XYZ.
