I am using adobe illustrator and trying to capture a certain aged aesthetic in the fill of my svg shapes. Here is my inspiration below from an old tapestry. I'm only interested in the background, so we can ignore the floral pattern:
The closest I got to that background was by drawing a square, then:
select square >> swatches >> swatch libraries menu >> gradients >> metals
From here I was able to use the eye dropper to replicate the color palette well enough, but I seemed to have lost the "aged" component of the fill:
I take the point that my needs are vast, because svg is working in crisp vector space and yet I want an aged tapestry fill like the inspiration. To keep things realistic, I am not looking to replicate at the pixel level, as Joonas pointed out, the SVG would be too complicated. But I still can't help but wonder, is there a way to achieve a convincing aged fill without coming across as overtly modern in terms of aesthetics? I'm trying to find a happy medium between the inspiration and my pure gradient; hopefully this kind of compromise would be palatable to the SVG format.
