Data.Colour.Rec601
Description

Defines the Y'CbCr and Y'PbPr colour spaces in accordance with ITU-R Recommendation BT.601 used for standard definition television (SDTV).

For high definition television (HDTV) see Data.Colour.Rec709.

Documentation
luma :: (Floating a, RealFrac a) => Colour a -> aSource
Luma (Y') approximates the Data.Colour.CIE.lightness of a Colour.
y'PbPr :: (Floating a, RealFrac a) => a -> a -> a -> Colour aSource
Construct a Colour from Y'PbPr coordinates.
toY'PbPr :: (Floating a, RealFrac a) => Colour a -> (a, a, a)Source
Returns the Y'PbPr coordinates of a Colour.
y'CbCr :: (Floating a, RealFrac a) => Word8 -> Word8 -> Word8 -> Colour aSource
Construct a Colour from Y'CbRr 8-bit coordinates.
toY'CbCr :: (Floating a, RealFrac a) => Colour a -> (Word8, Word8, Word8)Source
Returns the Y'CbCr 8-bit coordinates of a Colour.
