P: HSL values option (instead of RBG) under histogram

When I'm tuning colors in skin tones, the ability to see the colors represented as Hue, Saturation, and Brightness is beneficial. RGB colors are pretty useless except for picking neutral gray.

And as outlined earlier, there is Lab for that kind of color correction,

I've always wished that there was a preference for how the color sampler info is displayed under the histogram. When I'm tuning colors in skin tones, the ability to see the colors represented as Hue, Saturation, and Brightness is beneficial. RGB colors are pretty useless except for picking neutral gray. The ability to choose sample size as is available in Photoshop would also be beneficial.

Been a PS user since V1.07 and AFAIK, never a native HSL readout (HSB?). This is why we may never see this. Maybe an optional Adobe plug-in decades ago as I recall.

Another possible issue with HSL is the color space LR uses would (could) show 'illegal' colors considering it is based on ProPhoto RGB of which there are RGB values that are not within the scale.

Its obviously not a pressing issue for most...

But like the above user who suffers from color blindness, and like to double check color through numerical display values, it would be a handy product improvement. Its puzzling that it is available as a display in Info tab and color picker in Photoshop, and not Lightroom. Especially when HSL sliders are lower down in develop module.

"HSL has been used in Photoshop since 1990 for readout's where? "

Readouts? Im not sure, but I've used since Version 3.0, and HSL has been a display option in Info tab since then, and also as a value display in color picker panel.

I wasnt using Photoshop in 1990, but if this infomation is incorrect, I stand corrected.

They all ultimately provide the same data, just displayed in a different way...

One simply needs to make an effort to learn the scale. 

HSL has been used in Photoshop since 1990 for readout's where? 

I'm absolutely not opposed to HSL (or LCH) readouts in LR or Photoshop. I just don't ever expect we'll see it. And with a mere 4 upvotes in nearly a year here, that seems more likely the result. 

The reason I prefer HSL to RGB and Lab readout of color, is that HSL only uses one constant value for tone... which for skin tone, is what your trying to find.

RGB uses a fluctuating combination of three values, and Lab two values.

They all ultimately provide the same data, just displayed in a different way...

But you can have a whole range of RGB values and ab values of color that all add up to the same Hue value.

Hue provides a fast, easy, constant way of seeing a tone value. HSL isolates Hue/tone value, whereas RGB and Lab don't.

HSL has been used in Photoshop too since 1990

Lightroom was always designed to be a faster and easier program than Photoshop to process images. It would make sense to incorporate a color value display that uses one value, as opposed to a combination of 2 or 3 vaues, to display tone.

Anything new or unfamiliar is difficult to understand. 

"Learning is not attained by chance. It must be sought for with ardor and attended to with diligence. "-Abigail Adams

If you grew up on the metric system, the US system is difficult to understand and vice versa. 

Lab and RGB are easy to understand with an attempt and just a little study.

Lstar is simply Lightness separate from color. a* is the Red/Green color values, b*: Blue/Yellow Values. The video on correcting skin tones is easily learned. 

RGB is simple too; when R=G=B in a Working Space, you have a neutral. 

If you don't understand RGB, you don't understand how Histograms work (and there's a video for that too, just ask). 

HSL values would be isn't a  far better solution; it's a different scale. Suggesting it is a better solution is like saying the metric system is a better solution which again, is just a different scale.  

You tell us: "We have three users in this thread that use HSL in photoshop regulary to monitor skin tones, and I imagine there are a great many other in the Adobe community who would benifit from the addition of HSL to the Histogram value display"

Well get them to vote, otherwise, nothing will happen here. The facts are, Lab and RGB values have been in Photoshop for many decades, with perhaps millions of users being able to follow this scale. Maybe you can't. Maybe you can get more votes here (zero guarantees anything new from Adobe will result). Or maybe you can try learning the scale of color Photoshop has been using since 1990. 

Thanks for reply. 

LAB values are difficult to understand, much like RGB values.

HSL values would be a far better solution. We have three users in this thread that use HSL in photoshop regulary to monitor skin tones, and I imagine there are a great many other in the Adobe community who would benifit from the addition of HSL to the Histogram value display

I get the impression, trying to get in contact with Adobe developers is next to near impossible to suggest product improvements

Not at all:

Which is what we have here with three votes.

Of course, LR can show you Lab values.

You can easily nail skin tones using Lab.

Keep the data in RGB and just set the info for Lab. Looking over most of the good skin tone reference files I have, including the Roman 16*, aStar and bStar are often numerically very close and never more than 10-12 values difference. As seen here:

http://digitaldog.net/files/SkinToneLAB.jpg

In Lab, the aStar and bStar values are key. Both should be positive values. Both should be within 10-12 values units of each other. If the B value is lower than A, skin starts to appear magenta or pink looking. When B is higher than A the skin appears more yellow. The closer to zero, the more pale.

You may also note that in ACR, the Temperature and Tint sliders are effectively the same as the A & B channels of LAB. The Temp Axis (blue-yellow) equates to LAB B and the Tint axis (Gren- Magenta) equates to the LAB A.
