	28 .SH DESCRIPTION
	29 .B blind-primary-key
	30 reads a video from stdin and replaces a primary
	31 with transparency and prints the resulting video
	32 to stdout.
	33 .B blind-primary-key
	34 internally converts colour space to the one
	35 with the primaries whose CIE XYZ values are
	36 .RI ( X1
	37 .I Y1
	38 .IR Z1 ),
	39 .RI ( X2
	40 .I Y2
	41 .IR Z2 ),
	42 and
	43 .RI ( X3
	44 .I Y3
	45 .IR Z3 )
	46 and whose white point is the colour whose
	47 CIE XYZ values are
	48 .RI ( white-X
	49 .I white-Y
	50 .IR white-Z ),
	51 and replaces the first primary with transparency.
	52 If the white point is not specified,
	53 CIE Standard Illuminant D65 is used.
	54 .P
	55 If the colour space is specified, no conversion
	56 is done internally.
	57 .SH OPTIONS
	58 .TP

	64 of the first primary, with transparency.
	65 .TP

	72 .TP
	73 .B -g
	74 The video is, with the exception of the keyed primary,
