Is Your Browser Color Managed?

Nevertheless, I believe them to be fairly accurately managed for whatevere color profile I may choose for them. -- Regards, Eric Stevens |

| My browser is Firefox and I believe it is color managed. | Still a small factor, I think. People have different OSs, different monitors, different monitor settings... If a page depends on the browser recognizing color profiles then the webmaster doesn't know what they're doing. Webpages are simply not designed for that kind of precision. Nor are computers, for that matter. It's one thing to calibrate your own computer to your printer. It's another to expect that you can pass on that accuracy to someone else's machine. Interestingly, when I first went to that page I saw the yellow car. I then tried changing the Firefox pref for gfx.color_management.mode, trying to figure out what prefs might affect the display, but nothing changed. Actually, I tried the setting to always apply color management. Today I see the purple car in both Firefox and Pale Moon. Yet it was only in PM that I made any settings change in the first place, and I later changed that back to the setting to only apply color management for tagged images. I also see a purple car when I download the image and view it with various software. The author didn't explain how the purple vs yellow shows. When I look at the image bytes I see a simple JFIF, no EXIF data. |

People have different OSs, different monitors, different monitor settings... exactly the problem that colour management solves. If a page depends on the browser recognizing color profiles then the webmaster doesn't know what they're doing. nonsense. it show that the webmaster *does* know what they're doing and that they want people to see accurate images, which is why the images have embedded profiles. Webpages are simply not designed for that kind of precision. your webpages might not be, but plenty are. Nor are computers, for that matter. nonsense. It's one thing to calibrate your own computer to your printer. and the wrong way to do it. It's another to expect that you can pass on that accuracy to someone else's machine. something which works quite well. |

Why did you write that, even after snipping the bit where I wrote: "My monitors have been color magaed since before that article was written - except for now while I wait for the necessary X-Rite i1 to manage my new monitors. Nevertheless, I believe them to be fairly accurately managed for whatevere color profile I may choose for them." My monitor settings are as close to right as I can get them. If a page depends on the browser recognizing color profiles then the webmaster doesn't know what they're doing. Webpages are simply not designed for that kind of precision. Of course not! Any old splash of color will do. Nor are computers, for that matter. It's one thing to calibrate your own computer to your printer. You are giving a very strong impression of somebody who has not even the foggiest idea of what they are talking about. Only a complete innocent would try to get their printer colors right by doing things to their computer. They do things *with* their computer so as to send the correct color signals to their printer. This requires that first the printer, the paper in use and the ink, be used to derive a color profile for the printing. It's another to expect that you can pass on that accuracy to someone else's machine. Of course you can, if that other machine is properly calibrated and color managed. Interestingly, when I first went to that page I saw the yellow car. I then tried changing the Firefox pref for gfx.color_management.mode, trying to figure out what prefs might affect the display, but nothing changed. Actually, I tried the setting to always apply color management. Today I see the purple car in both Firefox and Pale Moon. Yet it was only in PM that I made any settings change in the first place, and I later changed that back to the setting to only apply color management for tagged images. Your problem is that you don't understand what you are doing. Fiddling with settings is not the answer. I also see a purple car when I download the image and view it with various software. The author didn't explain how the purple vs yellow shows. When I look at the image bytes I see a simple JFIF, no EXIF data. -- Regards, Eric Stevens |

My point was the part that *you* snipped. "It's one thing to calibrate your own computer to your printer. It's another to expect that you can pass on that accuracy to someone else's machine." In other words, when dealing with graphics on your own machine, calibration is relevant. When dealing with webpages or transferring graphics, one just has to settle for a range. Browser, OS, monitor, settings, graphics driver, a and of course a person's vision will all affect what's seen. You can only adjust for your own view. (Most monitors I see default to too much saturation and too bright. I don't know why. I'm guessing the device companies are trying to wow customers with "richness".) Years ago there were web-safe colors to attempt some kind of standard. Everyone agreed they'd try to do their best to have those colors show the same on all machines. They were the hex codes made up of 00 33 66 99 CC FF. (0033FF, CC6699, etc) The idea was that if you stuck with only those colors you could sorta, kinda depend on people viewing your webpage all seeing about the same colors. But even that was just an approximation. Color is also relative to lighting, surrounding colors, etc. Cream next to orange looks white, while next to white it looks yellow. Which is the real color? So what I'm saying is, you can calibrate your devices in order to print accurately what you see on your monitor, but that's the only relevant calibration. Once you send images to others, who view them on other devices, all bets are off. |

My point was the part that *you* snipped. "It's one thing to calibrate your own computer to your printer. It's another to expect that you can pass on that accuracy to someone else's machine." I diodn't snip that. Its there in my reply. You can't see it in your current reply because *you* snipped it. In other words, when dealing with graphics on your own machine, calibration is relevant. When dealing with webpages or transferring graphics, one just has to settle for a range. Browser, OS, monitor, settings, graphics driver, a and of course a person's vision will all affect what's seen. You can only adjust for your own view. (Most monitors I see default to too much saturation and too bright. I don't know why. I'm guessing the device companies are trying to wow customers with "richness".) Thats why devices such as http://www.datacolor.com/photography-design/ and http://tinyurl.com/lolsetm exist. Years ago there were web-safe colors to attempt some kind of standard. Everyone agreed they'd try to do their best to have those colors show the same on all machines. They were the hex codes made up of 00 33 66 99 CC FF. (0033FF, CC6699, etc) The idea was that if you stuck with only those colors you could sorta, kinda depend on people viewing your webpage all seeing about the same colors. But even that was just an approximation. Color is also relative to lighting, surrounding colors, etc. Cream next to orange looks white, while next to white it looks yellow. Which is the real color? Web-safe colors are *ancient*. They date from the days when many devices could only display 256 colors. See https://en.wikipedia.org/wiki/Web_co...eb-safe_colors So what I'm saying is, you can calibrate your devices in order to print accurately what you see on your monitor, but that's the only relevant calibration. Once you send images to others, who view them on other devices, all bets are off. First, we are talking about photography, for which web colours are not sufficient. Second all bets are off if you are sufficiently behind the times to be not using a color-managed work flow with the color profiles of calibrated equipment.
