.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 OPTIONS
.TP
.BR -F " "\fIpixel-format\fP
Select pixel format, see
.BR blind-convert (1)
for more information. Pixel formats starting with
.BR raw
are not supported.
.TP
.B -z
Parse arguments as CIE XYY instead of CIE XYZ.
.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.
