Difference Color Temperature

[stefanh45494374]

Hi 

Why do I have this difference depending color temperature between Lightomm (left) and Export (right - jpg Windows used as desktop background).

My monitor is calibrated.

Thanks for your help.

CCT Color Temp values define a pretty large number of possible colors and, everyone can calculate it differently. So I wouldn’t put much concern on specific values. This might help:

NOW, the issue in your enclosed PNG shows a color difference (not a WB difference per se) and I suspect that after you export the data, you are viewing it in a non color managed application. That is why it doesn't match LR which is color managed. Windows isn't color managing that data, so it's showing you an incorrect preview of the data!

It may not be possible to cause your desktop background to become properly colour managed for showing photos. Others have now explained your options better than I can.

If the monitor is wide gamut, just use Adobe RGB for a desktop background image. No special treatment required. It will look roughly right without color management (such as the Windows desktop) on a wide gamut monitor.

It will also look perfectly fine in color managed software everywhere and under all circumstances, as long as the profile is embedded. The Lightroom version in the OP is correct, and that's how it will look in all color managed applications everywhere.

Just don't use it for standard gamut monitors without full color management - then it will look dull and muted.

Hi there

Thanks for your answer.

What seems to be strange from my point of view, that the display in Google Chrome - 500px (upload from the jpg out of Windows) is equal to the Lightroom version (tif).

This is really simple: if the data is color managed, it matches other color managed applications. If the data isn't color managed, there's no guarantee it will match and it usually doesn't.

That's exactly what I'm saying. Read my post again. It means Chrome is color managed.

Chrome is now color managed:

In the past few years, the main browsers adopted sane color management strategies and defaults. In 2019, Safari, Chrome and Firefox all pass our browser color management test. Firefox now has the worst color management support for not interpreting untagged images and page elements as sRGB by default, requiring a manual configuration to do so.
