Mostly Color

Names vs. Numbers

Published 29 February 2008, 08:15 PM

By way of some background to the color thesaurus and the color zeigeist, I think it is interesting to do a quick visual example demonstrating the difference between using names versus numbers for color.

Looking at the example below consisting of six colored squares, how do the patches correspond to the table of red, green and blue or RGB values in the table above the patches? Take as much time as you need but try to keep track of how hard or easy it is to do this task.


Now compare the above example to the one below that includes a row for color names. How do the color names correspond to the colored patches? How do the color names correspond to the RGB values? Is it easier or harder to use the names or the numbers?


Hopefully it is clear that the example above with the names is easier to interpret than the example without the names. Below you can see arrows that connect the colored pacthes with the corresponding RGB values and names. In this case they are backwards.


So you can probably think of other examples but I suspect for any given color space like RGB, CMYK, CIELAB and so on a list of numbers is a lot less intuitive than a list of names. Stated a different way I suspect there is no color space or color encoding that exhibits a Stroop effect.

Maybe it is because RGB is tri-dimensional while name is just one-dimensional. In today's post you write Maya blue is #73C2FB, which is one-dimensional, and to us webbies it is clear what #73C2FB looks like. You just have to learn the right language.

Tamago1, Thanks for the insightful comment. The dimensionality difference between names and numbers is important. At some point we'll post some previously published results for an online experiment that looked at naming dimensionality - it's not quite one dimensional but it's also not quite three dimensional. I use hex color encoding quite a bit but must admit I can't always tell my shades of blue apart from just the hex data - now CIECAM02 coordinates that's another story. Nathan
