Graphics.Gloss.Data.Color

Contents

Description

Predefined and custom colors.

Synopsis

Color data type

data Color :: * #

An abstract color value. We keep the type abstract so we can be sure that the components are in the required range. To make a custom color use makeColor.

Instances

Eq Color 

Methods

(==) :: Color -> Color -> Bool #

(/=) :: Color -> Color -> Bool #

Data Color 

Methods

gfoldl :: (forall d b. Data d => c (d -> b) -> d -> c b) -> (forall g. g -> c g) -> Color -> c Color #

Num Color 
Show Color 

Methods

showsPrec :: Int -> Color -> ShowS #

show :: Color -> String #

showList :: [Color] -> ShowS #

makeColor #

Arguments

:: Float

Red component.

-> Float

Green component.

-> Float

Blue component.

-> Float

Alpha component.

-> Color 

Make a custom color. All components are clamped to the range [0..1].

makeColorI :: Int -> Int -> Int -> Int -> Color #

Make a custom color. All components are clamped to the range [0..255].

rgbaOfColor :: Color -> (Float, Float, Float, Float) #

Take the RGBA components of a color.

Color functions

mixColors Source #

Arguments

:: Float

Proportion of first color.

-> Float

Proportion of second color.

-> Color

First color.

-> Color

Second color.

-> Color

Resulting color.

Mix two colors with the given ratios.

addColors :: Color -> Color -> Color Source #

Add RGB components of a color component-wise, then normalise them to the highest resulting one. The alpha components are averaged.

dim :: Color -> Color Source #

Make a dimmer version of a color, scaling towards black.

bright :: Color -> Color Source #

Make a brighter version of a color, scaling towards white.

light :: Color -> Color Source #

Lighten a color, adding white.

dark :: Color -> Color Source #

Darken a color, adding black.

withRed :: Float -> Color -> Color Source #

Set the red value of a Color.

withGreen :: Float -> Color -> Color Source #

Set the green value of a Color.

withBlue :: Float -> Color -> Color Source #

Set the blue value of a Color.

withAlpha :: Float -> Color -> Color Source #

Set the alpha value of a Color.

Pre-defined colors

greyN :: Float -> Color Source #
