Land of Color reader, Hollie, left this comment on another thread.

I am trying to find information for Benjamin Moore color Paris Rain #1501. How do I find a chart similar to the BM Affinity Color notation charts that have harmony within hue families like the one above. Are there any other websites that would give me access to this easily. Thank You so much, Hollie Heil

I believe Hollie was referring to the table of color notations for all the colors in the Affinity color collection. Hollie wanted to know of other websites that published notations.

I’ll get to that answer at the end of the post. The information Hollie is looking for is the “Colorography” of Paris Rain; details about its intrinsic color characteristics. A color’s intrinsic color characteristics are defined by its spectral data. Spectral data comes from measuring the color with a professional, calibrated device using a standard that specifies the conditions for taking the measurement, like the light has to mimic daylight at noon in the shade, etc. So, that’s what I did. I used the spectral data for Paris Rain to make this infographic that illustrates on a special color wheel I made the color’s intrinsic characteristics. (click on the link and you can download the color wheel for free)

Once you know what hue family a color belongs to, then the basic rules of color harmony apply. In other words, it’s easy to know what colors go together.

No. Nobody else uses spectral data to ascertain color notations for major brand’s paint colors – it’s an approach that is unique to The Land of Color and Camp Chroma. While everyone has jumped on the bandwagon for other, purely subjective methods, I’ve been quietly and consistently introducing folks to classic colorimetry as an objective means to solve their color conundrums.

And that’s the reason I created Camp Chroma.

Just by reading other color expert’s, consultant’s and designer’s blogs and reviewing their past work, it’s quite obvious that The Land of Color and Camp Chroma is the only place in all of architectural color and design world that shows you what spectral data is and how to apply it to make choosing color faster, easier, and more accurate.

It seems the universe chose me to do something about spreading the word about colorimetry since I was the one with the expertise to combine spectral data and architectural color consulting. So, I developed an online color classroom called Camp Chroma and I teach people my craft, my trade. At Camp Chroma you learn about spectral data, color notations, color spaces, and systems – basically, everything you need to know about how to leverage the science of color measurement to specify color for the built environment.

    Hi Lori,
    Can you explain to me the difference between the Hue of 8.17Y and the CIE H° of 104° is. I think that the 104° comes from Easyrbg. And then the 8.17Y you calculate? But aren’t they both hue angles? If so, why are they separately noted on the Colorography above. Also, why is the Value and Chroma on RGB different from what you calculate and is that something that gets mapped separately? Sorry all the questions but I’m just confused.

  • Hi Cathy,

    8.17Y is a Munsell Hue notation – answering the question “If Paris Rain were a color in the Munsell Color Order System, what hue family would it belong to?”

    CIE H° of 104° is the CIE LCh hue degree – answering the question, “If Paris Rain were plotted in the CIE LCh color space, what hue family would it belong to?”

    Munsell and CIE LCh are two separate color spaces. CIE LCh was *modeled* after Munsell so they will always align. But since they are indeed two separate color spaces, they will never match up exactly when you plot a color on the color wheel.

    Same with value and chroma. There is the Munsell value/chroma notation and then there are the CIE LCh value/chroma values.

    Rule of thumb:
    Divide CIE LCh L value by 10, you’ll get pretty near a Munsell Value.
    Divide CIE LCh C value by 5, and you’ll close to Munsell Chroma

    These are good questions. As you go through the sequential Lessons in Camp Chroma all this stuff comes together and makes sense – each lesson builds upon the previous lesson.

    Hope that helped.
