Photoshop: HSL Color picker plugin?

Question

Is there a plugin that can let Photoshop use a HSL color picker, rather than HSV (which Adobe calls HSB)?

In other words, any/all of the following locations could have an HSL option:

Or perhaps a plugin with it's own color picker.

Reference

     RGB             HSL         HSV (aka HSB)
=============  ===============  ================
(1,   0, 0  )  (  0°, 1, 0.5 )  (  0°, 1,   1  )   
(0.5, 1, 0.5)  (120°, 1, 0.75)  (120°, 0.5, 1  )   
(0,   0, 0.5)  (240°, 1, 0.25)  (240°, 1,   0.5)   

Answer 1

There is a plugin called HSBHSL provided by Adobe Photoshop itself. Hope that solve your problem.

HSBHSL The "HSL&HSB" plug-in allows conversion between RGB and HSL (Hue, Saturation, and Lightness) and between RGB and HSB (Hue, Saturation, and Brightness) within Photoshop. This plug-in also allows you to change the Hue, Saturation, or Luminosity of an image as independent channels. Or, to change HSL/HSB using channel operations (calculations).

Photoshop uses both HSB and HSL according to this: http://www.worldlingo.com/ma/enwiki/en/HSL_and_HSV#Comparison_of_HSL_and_HSV

Maybe it's that "L" field on the right side? ;)
