Here is another view on the same problem. We discuss colour in terms of printer performance, inks and paper but here is an example that excludes all of these and shows that the human brain plays us false.
Print the attached image and cut it across the squares maked A and B. Slide the paper so that the two squares lie next to each other. Square A and B will have the same colour when viewed together but different when printed. Odd? |

So let me ask the basic question, is there any way short of a printing press to produce a true red color?

Once that is done, I'm certain it would be possible to find a combination of paper, ink, printing mechanism, and ambient light that would achieve equality with the reference definition. It's incredibly unlikely, however, that you could upload a file and expect different downloaders to be able to separately, independently, using their own printing mechanisms, reliably achieve equality with the reference definition.

Sort of related: over the last 6 weeks or so, Dad had cataract surgery in each eye. He remarked how much more vivid colors are after the lens replacement; he hadn't realized his color perception had degraded that much.

Guy goes to the corner store...finds it closed.
Sign on the door says "Open 24 Hours". Comes back three times during the following week to find the store closed each time. When he finally sees the store open, he goes in...and asks the Store owner: "I have visited your store numerous times and its always closed!" Store owner asks "whats your point?" "The sign on the door says Open 24 Hours?" he states. "Not in a row!" replies the store owner. ... Why can't things work the way we want them too? LOL Why won't my printer print the same colour twice in a row?

Here's another twist. I'm red/green colorblind, so what I see is different than what most other people see. Which is usually why I send models out to be test built. They also point out glaring color errors.

How many red/green models have you produced? lol
Now, if you said you were "white/gray colorblind" ...that would affect a large selection of your models! I have every colour deficiency that there is and yet I can still test build my own models. LOL I think you're stretching the excuses a bit there Murph! ... But, this brings us back to the problem of what comes out of your Printer. And for Designers, Printer control and consistency is a big concern. My colour blindness causes me to refer to colour sampling and colour codes. I never rely on my own colour judgement. I bring in images and samples of colours I wish to use on a model and regardless of what I think I see, I sample the colour and reproduce it within my artwork program. I also keep track of HTML/RGB/CMYK codes and match colours that way. I print out colour sheets/test swatches and make sure to include the necessary codes on those swatches and then I keep these sheets for future reference. I also keep colour sheets to show what colours look like when they come out of the printer rather than rely on what I see on the screen. If I have any uncertainty about the correct colour on a model, I ignore whats on my screen and print the sheet to see it in person and I usually show it to someone else for their verification of the colour(s). And I still test build my own models. lol

That is TOO wild!! Excellent example of why we shouldn't trust what we see on the screen! Because our brains get involved and everything goes to pot!! hahaha An excellent example of how I sample an image, get a colour code and use it to apply to my design work. ... I'll admit...I didn't believe you. I had to check for myself. And other than some slight pixel differences in the image, depends on where you sample, the colours are the same!
