does any any one have issues with posting on instagram? when posting an image are there a discoloration in image?
No. Unless you are looking at it from a different device, it should not cause your photos to look different.
Check what color profile you are exporting to. Make sure it’s srgb, not Adobe RGB or pro photo RGB. This can have a pretty major affect on what your images look like when displayed in srgb.
Make sure your JPG is sRGB color space. If it’s not, it will look washed out/muted on IG.
