CE: Color Editor to manipulates ARGB color values

Syntax

ce(color, filter, [amount])

Arguments

  • color: A valid ARGB or RGB color String (eg #FF663399)
  • filter: Filter ("alpha" opacity, "sat" saturation, "lum" luminance) or gradient end color (see examples)
  • amount: A value between 0 and 100, for alpha 0 is fully transparent, for saturation 0 means greyscale and for luminance 0 is black

Examples

Formula Description
$ce(#FF0000, invert)$ Will invert RGB color
$ce(#FF0000, comp)$ Will return complementary color
$ce(#FF0000, contrast)$ Return either black or white depending on best contrast
$ce(#FF0000, alpha, 50)$ Will make a fully opaque red into 50% transparent
$ce(#FF0000, sat, 0)$ Will convert red color into Greyscale equivalent
$ce(#FF0000, lum, 50)$ Will set red luminance to 50
$ce(#FF0000, lum, a50)$ Will add 50 to red luminance (0 to 100)
$ce(#FF0000, alpha, r50)$ Will remove 50 from red alpha (0 to 255)
$ce(#FF0000, #FF0000, 50)$ Mix half red and half blue (50% gradient)
