Chrome should be able to display it fine. The dl=1 param on the Dropbox URL means the request is served with a response header indicating it's a download. Change the link to dl=0 and it won't force the download.
By the way, anyone who can display it (all my nice monitors aren't with me at the moment) can you see it on this imgur link? http://i.imgur.com/qCna54M.png
imgur shows straight red on my 2015 Macbook Pro, but my iPhone 7 shows the logo.
The dropbox thumbnail link (with ?dl=0) shows the logo. Opening the link with ?dl=1 in Preview shows straight red. I think Dropbox is doing some weird thumbnail processing.
I wonder if it has to do with imgur compressing the image, or maybe approximating/ignoring the colorspace as was mentioned above.
