As I understand it, this is a color test problem. But I have a standard color test sRGB for export everywhere. On my computer, the white color is a little pinkish, on the iPad everything is the same, but when I send a photo to my clients and friends or to my phone (iphone 11), our white color is greenish. That it is impossible to save photos so that they are more or less the same on all devices?
This is an example of a slightly pinkish white, which is how it should be. If you do not see pink in white, then this is not normal. It should be pinkish. On phone is white greenish.
