Cheers Ron. Good to get a result.

SRGB is a colour space, essentially a way of mapping numbers (which is all a digital camera or a phone or a computer understands) to colours (which is all that we can see). There are many different colour spaces, nearly all of them designed for specific purposes. The standard colour space is sRGB. Nearly everything uses it. The only thing you really need to know about colour spaces is that sRGB is the one you want to be using and (almost always) the one you get unless you go fiddling with things. As background, there are reasons to use other colour spaces but use of them is technical and requires specialised knowledge, software and equipment. A good rule of thumb is that if you don't know anything about them, then you don't need to know anything about them except to stick with sRGB if the question ever comes up, which it mostly doesn't.
