Properties

blue

the blue component of color

getColorBlue :: MonadIO m => Color -> m Word16

Get the value of the “blue” field. When overloading is enabled, this is equivalent to

get color #blue

setColorBlue :: MonadIO m => Color -> Word16 -> m ()

Set the value of the “blue” field. When overloading is enabled, this is equivalent to

set color [ #blue := value ]

green

the green component of color

getColorGreen :: MonadIO m => Color -> m Word16

Get the value of the “green” field. When overloading is enabled, this is equivalent to

get color #green

setColorGreen :: MonadIO m => Color -> Word16 -> m ()

Set the value of the “green” field. When overloading is enabled, this is equivalent to

set color [ #green := value ]

red

the red componment of color

getColorRed :: MonadIO m => Color -> m Word16

Get the value of the “red” field. When overloading is enabled, this is equivalent to

get color #red

setColorRed :: MonadIO m => Color -> Word16 -> m ()

Set the value of the “red” field. When overloading is enabled, this is equivalent to

set color [ #red := value ]
