Title: Wired — a contender for the worst reporting on color ever.
Post by: MarkM on April 10, 2015, 02:28:28 pm

I know, poor reporting about color science is not surprising or unusual. But I'm not sure I've ever seen it so bad in such a large publication:

My favorite quote:

…like CMYK (cyan, magenta, yellow and black) and RGB (red, green, blue). Both of those gamuts exist only in two dimensions.

Seriously…is it that hard?

Shocking. At least the author is being called out in the comments. I would have thought better of Wired.

I love the idiotic comment “this has never been done before”. GamutViewer from X-rite, ColorThink Pro from Chromix, to name just two products has been doing this for at least a decade. And so thanks to this hype, a grant? Ridiculous.

I can't tell if the article is poorly written or the author isn't understanding what he's talking about, maybe a bit of both. It goes in and out of something that resembles logic but nothing about color that makes sense at least to me as a former illustrator and graphic designer.

First he says a couple of artists and a physicist are collaborating to create software that can name colors that don't currently have a descriptive name and then says they're going to use a number system as the naming convention which has never been done before. WTF?! Are they kidding? It's been done before ad nauseum. I can't believe the physicist didn't tell them.

And they're going to get a government grant for that?!

Here's a useful guide for Pantone colors, some outside of AdobeRGB gamut, defined in Lab space...

Anyone here with software that can place a pantone color within a 3D gamut map?

I'm curious to see where Pantone 313C "rich cyan" is located. It's a color my DSLR and display can't reproduce but I found on an inkjet print off a Fuji Frontier drylab at my local Walgreens.

I located the closest match on my aging 747XR Pantone Color Formula Guide swatch book as 313C (L*52, a/-46, b/-44).

Just curious where it lies within a 3D gamut model.

ColorThink Pro can do this, you’ve got Lab values.

(L*52, a/-46, b/-44) falls outside Adobe RGB (1998). No problem with ProPhoto RGB.

Beautiful!

Then my eyes and the ICC profile 3D model of that printer compared to AdobeRGB in Colorsync I downloaded from Fuji's European site weren't lying to me.

Thanks a lot, Andrew.

Too bad you can't link to this more informative thread in that Disqus comment section of that ridiculous article.

I'm getting me some grant money! ;D

I wouldn't.  It's articles are frequently misinformed, although this one plumbed new depths.
