I'd email the company and ask.

That's a good idea Anglo. Thanks!

I don't think they publish it anywhere. There's another way that's slightly involved but I'll tell ya how to do it. Go to easyrgb.com

Find similar colors in different collections Click Try it now

Enter Color number

Choose Your Color

Click Compare

Click on your color name/data in the big colored square

Click Convert in the pop-up window

You are now on a page full of spectral data (color DNA) about your color.

Look for XYZ

The middle number, Y, is LRV. For example, Elephant's Breath is 52.976.

Only the capital Y in XYZ and Yxy is LRV.

The LRVs on easyrgb.com may or may not exactly match the LRV from the paint brand. They'll be close and that's okay.

You might find some colors listed twice or three times in the big colored square of spectral data. And the numbers might not match exactly. That's okay too, they will be close.

It's because the color appears in more than one fandeck and it was measured multiple times. Different, physical paint chips were measured resulting in slightly different numbers. Again, that's okay and to be expected. . . because different chips/samples.

Oh my gosh! It worked pretty darn good! The closest match was Brickyard Clay by Ben Moore with an lrv of 17.82. Amazing! Thanks Lori!!!

So, the Farrow & Ball color was Book Room Red, right?

Yes it was!!

Book Room Red LRV is 19.2

Brickyard Clay LRV is 19.6

Not sure where you got 17.82?

I'm curious, too; not about the LRV, but they're very different colors.

Sis2two, were you trying to match the colors by the LRV? Or did you just want similar depth of color?

Lori- I must have looked at something else or just remembered it wrong. I know that Brickyard Clay was the closest match according to that site.

My3dogs- mainly I just wanted an idea of the light reflective value of the Book Room Red. I got the sample of the Brickyard Clay from Ben Moore and they are very close to the same color. It's funny because I have the F&B fan deck and the color irl looks nothing like the color on my computer monitor.

The colors are very similar. One of the better matches to a F&B color I've seen actually. The digital swatches are way off for both.

Lori- what has your experience been with Farrow and Ball paint? On the F&B site, some of the reviews of the Book Room Red's coverage were not good. I've used Aura in most all of my rooms and I know it covers well. I know that F&B's undercoat is suggested so would you think it would need more than 2 coats to cover well? And I would rather not try to color match this particular color. Thanks.

I'm looking at both swatches. Honestly, if it were me I'd have it color matched and buy it in Aura. Brickyard is so similar and that's a good indication they should be able to match the F&B color easily. There's no reason an earthy red like this should require an undercoat and two top coats.

I'll go to Ben Moore in morning and get a small tester pot made up and see. I hope it matches. Also, do you think this particular color would work next to a Powell Buff foyer? Currently I have a Red that I don't like next to the PB. Thanks!

Yes. Gorgeous.

So happy to hear that!!

F and B paints have far more pigment that custom mixed paint. Where deep colors are concerned, it's well worth the money. I have heard of painters thinking they're doing there clients a favor by thinning it down to go further. BAD idea! I had my guest room painted with F&B Pelt, a dark color. It went over white walls and one coat covered beautifully. It's truly wonderful paint - really nothing like it in the US.

We have a great painter that we use and I don't mind spending the money on the F&B paint, but if it's going to take 4 coats, as some of the reviews said, then I will definitely use Ben Moore. I was originally thinking an undercoat and two coats of paint. The problem is that until the actual painting is underway, I'm not sure how to know it won't need several coats.

I will be covering a red color already so not sure if that will make a difference or not.

And is F&B a relatively thick paint compared to Ben Moore?

Oops, I was curious who Irv was. Irving?

It refers to the light reflective value of a paint. The higher the number the more light it reflects. Lori can explain it way better than me though.

sis2two summed it up perfectly. It refers to the light reflective value of a paint. The higher the number the more light it reflects. It runs on a scale from 0% to 100%. LRV is strictly about light and dark value, brightness and luminance. LRV is derived from color measurements, spectral data. In spectral data terms it is expressed as CIE Y. (which ties back to how to look up LRVs for F&B colors on easyrgb.com's tables of spectral data)

It has nothing to do with vividly pure or dulled grayness. Vivid and dull is a different dimension of color often referred to as grayscale, saturation, chroma or intensity. Grayness is perceptual and is derived from visual comparisons.

or grayscale in Munsell Color System terms

Sorry, I was kidding. Figured it out with the first responses. But thank you for the in-depth explanation of lrv. Very helpful!

Lori- thanks so much for taking the time to weigh in and explain things. I can't wait to try a sample from Ben Moore today.

nosoccermom- thought you might have been kidding but I never assume things anymore,lol!

Lori- can I ask your opinion as to whether Maple Leaf Red by Ben Moore can be used successfully in a room off of Powell Buff hallway? Thanks so much!

Yes - very pretty.

The Book Room Red wasn't really what I was going for after I got samples up. So I am trying to decide whether to keep my Maple Leaf Red or go with a more brownish red such as Onondaga Clay. Do you have any thoughts?

What's the reason for the red? Is there wallpaper, fabric, furniture, etc.?

I like a farmhouse style and feel like the right red really compliments my pine pieces/ black Windsor chairs that I'm using. I also have a large black and white folk art sign that I'm using. I have a Barn red color also in my family room rug that would tie into the dining room color as well. Currently I have the MLR in the dining room but have been debating whether to change it to a more brownish red or leave as is.

Powell Buff, Lenox Tan and Nantucket Gray are other colors that can be seen from the dining room.

I have a Barn red color also in my family room rug that would tie into the dining room color as well.

Then that's what needs to inform the red for the dining room. Doesn't have to "match" exactly but the red for the dining room walls should share some of the same characteristics as the barn red color in the family room rug.

That makes sense to me as well. Thank you!

I know, I’m only 5 years late with the answer😄 but it might be useful for someone searching right now

https://www.e-paint.co.uk/lab-hlc-rgb-lrv-values.asp

We also have Farrow & Ball LRV values in the Paint Color DNA Table. All I wanted was a list I could sort, so I made one.

I have all the newer colors and several archived colors. Can add any that are missing just email lori@thelandofcolor [dot] com

thanks so much! that table is amazing

Thank you so much! Ive been searching for LRV for F&B for a looooong time. Your method totally works!
