Hello @L_B, and welcome to the forum!
Your main issue will be that your displays arenât calibrated, only calibrated displays are capable to show always the best possible and identical ââexpressionââ of your pictures.
The next thing would be the different capabilities of each display you use, similar to cars, all will drive you from A to B, but some are faster, others more comfortable. In the world of displays, this means that there are displays that can display more (or fewer) colors than other displays, some use different color-spaces, which you can think of like different dialects of one language, all of them tell the same story, but you can understand them more or less easy because they sound different.
Now, there are technical ways to make a picture looking nearly identical on every used display, but there are displays, like those from mobile-phones, that can not be calibrated from the end user, these will always show slightly different colors. And the ones that can be calibrated, must be calibrated and match some other conditions to show always a nearly identical picture.
I assume that you, with your understanding of this complex issue, do not use calibrated displays, this means in reverse, you will never experience nearly identical images on your displays, and if so then only by chance.
And from here on I am out, because Iâm no specialist when it comes to color, I only can show you an overview of this.
But if you use Kritaâs standard-settings, it is strongly advised to stay with them and to assume (and hope) your computerâs display shows the colors in the best possible way if it is not a (low-)budget display, and to assume the other used displays do a bad job. But this is only an assumption, and it can be a bad advice because I donât know your display and its specifications.
I donât know if the further advice of a more expert user will help you, but if you are not satisfied with my advice, then please ask for further clarification here, or even for advice on at least some remedial action.
But with not calibrated displays and not understanding the topic itself, it is often better to accept the current state, if you donât want to acquire the needed knowledge by learning them.
But it may make sense for you to find a knowledgeable person to explain this topic to you in your language, then some hurdles in comprehensibility will be removed faster than by us, who can only try to explain it to you in English.
Anyway, I wish you a nice day and much fun with Krita!
