Graphics.Gloss.Data.Color

Predefined and custom colors.

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.

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

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

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

dim :: Color -> Color

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

bright :: Color -> Color

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

light :: Color -> Color

Lighten a color, adding white.

dark :: Color -> Color

Darken a color, adding black.

withRed :: Float -> Color -> Color

Set the red value of a Color.

withGreen :: Float -> Color -> Color

Set the green value of a Color.

withBlue :: Float -> Color -> Color

Set the blue value of a Color.

withAlpha :: Float -> Color -> Color

Set the alpha value of a Color.
