I wich to do as realistic render as possible, and wonder about optimal world color for this purpose. I know that many people use HDR images as world texture. May be this is the only option, but someties this images are hard to find and do not provide desired color. So i just wondering what world color you use to make your renders as realistic as possible?
There 40+ free hdrs at sibl
It’s not like there’s one world color which is better, and it also is not an either/or with rgb color or hdri. You can use mix rgb nodes and HSV nodes to change the hdri to the hue you want , or mix it with a color using a mix rgb node. If you increase the mix factor of the mixrgb up high you get nearly pure color, but a little bit of dynamic range.
The hdri is claled ueno-shrine from sibl

The color of your “ambient lighting,” in any photographic situation, depends on what you want to do, and, to a lesser extent, on the medium (printed, or projected) that you are [literally …] shooting for.
“The ambient color will be ‘the white.’” It won’t be “white,” of course, but it will be the foundation color against which everything else is viewed and considered. It will take the role of “the neutral tone,” but it won’t be neutral, and that’s the point.
The influence of this color will be most prominently seen in dark places, where of course it won’t be “seen” because those places are “dark.” A major role of this color is to ensure that none of these areas are opaque blackness (or whiteness): places where “there is no ink,” or “there is nothing but ink,” both of these being objectionable “places where no image exists at all.” A role of this color is to circumscribe limits around the tonal range and the color-gamut of the overall image. These are purely-technical considerations, over and above your artistic vision for the piece.
These things matter no matter what technology is being used to capture and then realize the image. What “books on film photography,” “books on videography,” and “books on printing” say about these issues, are all equally relevant.
