Color data type
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.
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].
makeColor' :: Float -> Float -> Float -> Float -> Color Source #
Make a custom color. You promise that all components are clamped to the range [0..1]
Arguments
| :: Int | Red component. |
| -> Int | Green component. |
| -> Int | Blue component. |
| -> Int | Alpha component. |
| -> Color |
Make a custom color. All components are clamped to the range [0..255].
Arguments
| :: Float | Red component. |
| -> Float | Green component. |
| -> Float | Blue component. |
| -> Float | Alpha component. |
| -> Color |
Make a custom color. Components should be in the range [0..1] but this is not checked.
Color functions
Arguments
| :: Float | Ratio of first color. |
| -> Float | Ratio 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.
Pre-defined colors
A greyness of a given magnitude.
Primary
Secondary
Tertiary
aquamarine :: Color Source #
chartreuse :: Color Source #
