Lighter

Lighter[color]

represents a lighter version of the specified color.

Lighter[color,f]

represents a version of the specified color lightened by a fraction f.

Lighter[image,…]

gives a lighter version of an image.

Lighter[video,…]

gives a version of a video with lighter frames.

Details

  • Lighter can be used to create a lighter version of a color or an image.
  • Lighter[color,1] gives white. »
  • Lighter[color,0] gives color. »
  • Lighter[color] is equivalent to Lighter[color,1/3]. »
  • Lighter[color,f] for values of f outside the range 0 to 1 are clipped.
  • Lighter[image] works with 2D as well as 3D images.
  • Lighter[{col1,col2,…},…] gives lighter versions of each of the coli. »
  • When applied to color, Lighter always returns an RGBColor.
  • When applied to color images, Lighter always returns an RGB image.
  • Lighter does not affect the opacity of a color or an image. »

Scope  (9)

Data  (6)

Lighter version of a color:

Lighter version of a 2D grayscale image:

Lighter version of an image:

Lighter automatically threads over colors:

Parameters  (3)

The default lightening fraction is :

Specify different darkening fractions:

With a lightening fraction of zero, the color is unchanged:

With a lightening fraction of one, the color becomes white:

Applications  (4)

Use Lighter to construct ColorFunction for plots:

Use Darker and Lighter values of a particular hue as a color function:

Make a dark, starry sky brighter:

Enhance a dark region of an image:

Properties & Relations  (5)

Lighter of a color is always returned as an RGBColor:

The opacity value is unaffected by Lighter:

Lighter is a special case of Blend:

Lighter and Darker are not commutative:

Lighter for images is a special case of ImageAdjust:

Possible Issues  (3)

Values outside of the 0–1 range will be clipped:

Some colors may look faded during the lightening:

Lighter behaves differently when applied to a color and an image pixel of the same color:

Interactive Examples  (1)

Observe the changing chromaticity of a color image as the image is made lighter:
