Hello,

since Inkscape uses HSL-color space in the fill and stroke dialog the saturation slider behaves very different compared to GIMP, PS or Illustrator, which use HSB-colorspace.

I wish inkscapes saturation slider would also be based on the HSB-colorspace.

Am I the only one who find this confusing?

Applications that use HSL color space:

• The CSS3 specification
• Inkscape (starting from version 0.42)
• Macromedia Studio
• Microsoft Windows system color picker (including Microsoft Paint)
• Paint Shop Pro
• ImageMagick
• … ?

For an in-depth discussion comparing both formats, see for example HSL and HSV encyclopedia topics | Reference.com. (The same topic in HSL and HSV - Wikipedia seems more generic in its description and less focused on the differences of the two color models)

Inkscape uses HSL since version 0.42:

Release Notes 0.42 wrote:

• In the color selector widget, the HSV tab (Hue, Saturation, Value) is replaced by HSL (Hue, Saturation, Lightness). The HSL color space is similar to HSV but is more convenient because it better reflects the intuitive understanding of what “saturation” and “lightness” are:
  
  
  • In HSL, the Saturation component always goes from fully saturated color to the equivalent gray (in HSV, with V=max, it goes from saturated color to white, which is counterintuitive).
    
  • The Lightness in HSL always spans the entire range from black through the chosen hue to white (in HSV, it only goes half that way, from black to the chosen hue).
