After finding myself frustratingly trawling the internet for an easily accessible table of Munsell system colours and their RGB (red, green, blue) conversion values, I set about putting up a copy of all those I have converted myself for other keen soil scientists and house renovators to make full use of. This list is by no means complete: please let me know if there's a particular colour on the list whose value you are desperately after, and I'll see what I can do! Currently listed Munsell colors: 10YR, 7.5YR and plenty more to come!

The difficulty with any blanket conversion is that it can only be an approximation because RGB values do not specify device-independent colours. For example R000 G000 B255 is distinctly purplish blue on my desktop monitor, but not at all purplish on my laptop. This has nothing to do with lack of calibration; it is simply that the 'blue' phosphors used in the two are different colours. A purplish blue gives a bigger gamut at the cost of energy efficiency, which is given higher priority in the manufacture of most laptops than in desktop monitors. With that proviso, though, Zsolt Kovacs' free program rs2color can be used as a colour calculator for conversion between Munsell, RGB and Lab (Windows only, XP to 7). It's always a shock to be roaming the www for pages of interest, and then seeing that they come from someone just down the road (I'm in Clovelly!).

David Briggs. David, it sounds as if one of your computers does not have the proper ICC profile for its monitor.

Jpegs, pngs, and so forth are made to a precisely defined perceptual spec called sRGB. In other words, sRGB pixels define how things should LOOK, not raw voltages to send to the monitor. It is up to the computer or the monitor to translate intent to signal levels. However, there are approximations involved in converting from Munsell to sRGB. That is because the only Rosetta Stone available to the masses is the 'renotation' data-set which was collected in the 30's under a weird and obsolete illuminant called 'C'. One must do chromatic adaptation.

I have written software to do it. Undoubtedly Macbeth has excellent data, but they are very stingy with it. They do publish the sRGB numbers for their Color Checker cards. My program agrees with those numbers to within the limits of perception. Thanks for the link.

I expect that I will just try and work with someone who knows more about this than me. I've already learned a lot about printers and their individual idiosyncracies--more than I ever wanted to know! I can now see why Munsell charges so much for their books.

Looking forward to any more work you do in the YR family. It helps when I'm in photoshop as I can make my own chips to add to the palette. Clovelly, England(?)is not near me.

I live closer to Toronto but have friends near London England and my dad originally came from Lancashire. Have been across the pond a couple of times and always enjoy learning more about it. Good luck with your research. Delete A File From The Ifs.

Learn How Munsell Color Space Sparked the Genesis of Today’s Color Space Models Whether you’re a student, teacher or curious consumer, you’ll find helpful color charts like the Munsell Hue, Value, Chroma Poster and three-dimensional color space tools like the Munsell Color Tree. Each tool depicts Munsell color space in a unique format that optimizes the learning experience from static color space charts and three dimensional models to an interactive learning kit—ideal for teaching color space in classrooms. After all, was an educator in addition to being an artist. Get a Hands-On Perspective of Color Space Models From any of the Following Munsell Color Space Tools As an artist and an educator, Albert H. Munsell transformed complex into a simple, practical system using color space charts and models. Munsell color space models are still used today to educate business, government and academia on color theory and the value of color. After all, Albert H.

Munsell was an educator in addition to being an artist. A Crash Course in Munsell Color Space Albert H. Munsell was an artist and an educator.

He developed his color theory to bring clarity to color communication by establishing an orderly system for accurately identifying every color that exists. Munsell based his system on what he defined as “perceived equidistance” — the human visual system’s perception of color. Munsell color order system is based on a three-dimensional model depicted in the Munsell color tree. Each color has three qualities or attributes: • Hue – color such as red, orange, yellow, etc. • Value – the lightness or darkness of a color • Chroma – the saturation or brilliance of a color Hue, value and chroma are also referred to as (HVC).
