✖
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,…]

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. »
