Usage
colour_burn(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.
Examples
colour_burn("#FFA600FF", "#8991A1FF")
Blend colours and palettes using colour dodge mode
Description
Brightens the destination colour to reflect the source by decreasing contrast. Produces bright, washed-out results.
Usage
colour_dodge(...)

Blend colours and palettes using darken mode
Description
Darkens colours by selecting the darker of two colour values for each RGB channel. Useful for creating shadows or combining dark elements.
Usage
darken(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.

darken("#FFA600FF", "#8991A1FF")
Blend colours and palettes using difference mode
Description
Subtracts the darker colour from the lighter. Identical colours produce black; white inverts the other colour.
Usage
difference(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.
Examples
difference("#FFA600FF", "#8991A1FF")
Blend colours and palettes using exclusion mode
Description
Similar to difference but with lower contrast. Identical colours produce grey rather than black.
Usage
exclusion(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.
Examples
exclusion("#FFA600FF", "#8991A1FF")
Blend colours and palettes using hard light mode
Description
Combines multiply and screen depending on the lightness of the first colour. Like overlay but the first colour controls whether darkening or lightening is applied.
Usage
hard_light(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.
Examples
hard_light("#FFA600FF", "#8991A1FF")
Blend colours and palettes using lighten mode
Description
Lightens colours by selecting the lighter of two colour values for each RGB channel. Useful for creating highlights or combining light elements.
Usage
lighten(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.
Examples
lighten("#FFA600FF", "#8991A1FF")
Blend colours and palettes using multiply mode
Description
Darkens colours by multiplying them together. Creates darker, more saturated results. Useful for creating shadows, darkening backgrounds, or adding depth.
Usage
multiply(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.
Examples
multiply("#F0F0F0", "#808080")
multiply("#FF6B6B")
Blend colours and palettes using overlay mode
Description
Combines multiply and screen depending on the lightness of the second colour. Values below 50% grey are multiplied (darkened); values above are screened (lightened).
Usage
overlay(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.
Examples
overlay("#FFA600FF", "#8991A1FF")
Blend colours and palettes using screen mode
Description
Lightens colours by inverting, multiplying, then inverting again. Creates brighter results. Useful for creating highlights, lightening backgrounds, or adding luminosity.
Usage
screen(...)
Arguments
... |
Either one or two colour/palette arguments:
|
Value
Character vector of blended colours or a blending function.
Examples
screen("#2C2C2C", "#808080")
screen("#4A4A4A")
