At least you seem to know what you mean…
Is there a plugin that can do what? What should this be on the PC-side that you constantly refuse to describe?
I don’t know if you knew this, but so far the broad mass of humanity is not yet able to read the thoughts of others, then of course we would know “what you mean”, but with such empty statements we have to rely on guesswork at best.
The nice thing is that at least you know what you mean. If you had written this down in descriptive terms for non-telepaths, you would probably have already received a more solid statement from us.
I really don’t get how you seem to know exactly what you want, but are unable to describe it in a way that could be easily understood by those you ask for support.
But due to years of experience, and because I only got a limited amount of time on this world, I’ll try to shorten the process and would guess you are searching for a tool that allows you to pin reference-pictures to the window of Krita and grab color-information from the pinned reference pictures.
Tools like: Plugin - Reference Tabs Docker or the wonderful and very versatile: Imagine Board plugin could probably be what you are after, but these are only shots in the dark, I have no idea if they hit the target.
So, if I guessed wrong, what is not impossible, would you be so kind to describe what you want in a way that could be understood by people without magic crystal-balls? And we also need to know the operating system of your device, so macOS, Linux, Windows, Android?
