Help with EasyRGB

4 years ago

Awhile back, folks here introduced me to EasyRGB. At the time, I was able to figure out how to find the color data for a particular paint, then to use the same website to look for colors with similar data but lower chroma.
But now I can no longer figure out how I did that. Hoping the folks who know how to use it are still around and fan remind me? Thanks!

    You have to pull the L*Ch(ab) from the data values page first. Highlighted in yellow.




    Go back to Home page

    Match Color Data

    Try it Now

    Select Data Type (first drop down) > CIE-L*Ch° (ab)


    You can adjust all three dimensions from here.



    C = Chroma in the CIELAB color space and the numbers are going to be bigger compared to Chroma in the Munsell color system.


    I have Munsell hue/value/chroma in The Color DNA Table (it's a $9.99/mo subscription on my website - full disclosure).


    My Table functions differently from EasyRGB because there are multiple ways to sort and order the 5,200+ colors using the little black arrows next to each column title.


    For example, these are Sherwin-William's White ordered by Chroma. < 0.51



    These are the best two options for finding, sorting and ordering paint colors. Each works differently from the other.


    It depends on how you want to search color attributes.

    An additional note about the CIE L*a*b* Youtube video. I recorded that for people in my private FB Group and they know that CIELAB is a 3 dimensional space. When you move redness, greeness, blueness, yellowness it's not necessarily is in a literal straight line.


    It's worth playing with the Lab numbers to see what you get but I want to be sure to set realistic expectations for results.

    I watch both videos and a lot of great information. If I use easy RGB and match BM Edgecomb Gray and BM Clay Beige the Hue seems close but the Edgecomb Gray chip looks a lot more gray. Is there a way to get more detail such as Chroma for each to determine the difference. Here is the data for Edgecomb Gray CIE-L*Ch(ab) = 84.069 7.641 90.373° and Clay Beige CIE-L*Ch(ab) = 82.991 11.058 89.198° . Thank you for all the information.

    Right now my bedroom walls are BM Richmond Bisque which I love, but I wanted to lighten it up a bit. 

    I think I've found some good candidates with BM Flawless, Secluded Beach, and Creamy Beige

    Did you use the Easy RGB to find the lighter colours?

    but the Edgecomb Gray chip looks a lot more gray. Is there a way to get more detail such as Chroma


    Yes. Colorfulness/grayness is the dimension of Chroma.


    Clean and dirty is what many people call it. And they think they have to eyeball clean/dirty. Totally not necessary. Just compare Chroma values.


    The problem with comparing LCh Chroma ("C" in LCh) numbers is the scale of the CIELAB color space. The numbers run big so it's harder to get your head around; one of the reasons why easyRGB isn't the most user-friendly.


    A Munsell notation is much easier to navigate and then visualize the color in your head. Because the numbers are smaller and IMO a Munsell notation does a better job describing Chroma (colorfulness).

    Hi Lori. I was also considering Elmira White so hoping you can provide this information as it seems to be the same as Edgecomb but a bit less gray so wondering if I am seeing that correctly.

    Correct. Elmira White is more colorful and Edgecomb is more grayed (neutral).


    If you put the chips in order like they're listed you can also see the gradation of hue with Elmira being the closest to the Yellow-Red hue family, Edgecomb is deeper in towards the middle of the Yellow Hue Family - you can use hue° or Hue Family. Either way results in the same gradation relative to hue family sectors.

    Would you mind adding Ballet White to compare. If the Hue is 94 or 3.18 would it make it more yellow compared to Edgecomb Hue of 90 or 2.02. This makes it easier to understand if I have it correct.

    Which is more yellow is a close call because they're similar with BW being lighter.

    Thank you. I see that is where the difference is in the colours. Appreciate all your help.

    👍🏻 Edgecomb Gray and Ballet White are so close that I could agree with calling Ballet White a lighter version of Edgecomb.

    I tried Edgecomb but it was a bit too light and blah looking and also showed a bit of pink. I tried Revere Pewter and it looked very nice but a bit dark and a touch of green. Would Natural Cream be close to Revere Pewter but lighter or if you have another choice that would be great. Thank you.
