That is what it looks like on my phone and laptop 

[My colors aren't true and don't export true]

I went to a website to get the color code and the color wasn't true to the website, but I thought it was just my computer so I exported and put it in drop box when I went to the Dropbox app on my phone the colors matched the website perfectly, but then I saved it and they matched my computer.

Does anyone know how to fix this?

I attached the saved photo and screenshot shot of Dropbox
