P: Brighten the Histogram as LrC 13.0 histogram is much darker than LrC 12.5

In LRC 13.1 the colors in the histogram can hardly be distinguished. For example the yellow curve is now almost green.

If somebody high up on the food chain at Adobe has a strong personal affinity for the new histogram, is there any reason they (Adobe) can't just give us a switch to go between the V12 histogram - which was pretty good - and the V13 histogram - which was pretty awful and is now slightly less awful, but still not as good as the old one.  Simple option in the preferences...

I understand that every time a new version comes out Adobe has to change stuff that was working fine for years.  Sometimes, it's an actual improvement, but sometimes it "breaks" something that's been fine for a decade... 

The histogram in 13.1 is a big improvement, but yellow now displays as green with a slight yellow tint, very similar to green.

Magenta displays as a slightly magenta blue, and I haven't been able to identify cyan.

In the old histogram (version 12 and earlier) it was easy to identify these secondary colors.

As this idea has been marked as released, I've created a new post:

https://community.adobe.com/t5/lightroom-classic-ideas/bring-back-histogram-gridlines/idi-p/14302305#M20809

I prefer the histogram as it is displayed in ACR.  

The features requested here have not been fully implemented. There are no histogram gridlines.

Please bring back the histogram gridlines. The current histogram is a step backwards in terms of usability.

Greetings all,

Updates for Adobe Photography products have been released.  The December updates have implemented this feature request.

If you do not see the update in your Creative Cloud Application, you can refresh it by hitting [Ctrl/Cmd]+[Alt/Opt]+[ R ].

Note: It may take up to 24 hours for your update to be available in your Creative Cloud app.

Thank you for your patience.

I like the old look from 12.5. much more, it was easier to use.

Hello, I often find it difficult to work with the new histogram look in Lightroom Classic. It's harder to see slight color changes when I need to adjust the correct WB or compare colors between images in slightly changing conditions.
And sometimes it just looks messy like lines with color bars.

The older look was (in my opinion) simpler and easier to use when i needed to see small color differences.

I also agree with the negative comments about how the new histogram is displayed.  It is dark and lacks contrast, and it is almost unreadable on my monitor.  Also the numbers under the histogram (ISO, focal lenght, aperture, and shutter speed) are hard to read.  The RGB numbers are very visible when the cursor is on the image.

The other panels on the right side of the develop module are ok for readability.  Please change the histogram back to its more visible presentation, or give us a option to choose the display format (old or new).
