Exporting to PDF and EPS in illustrator causes matte colors
Hi.
Recently when I export my illustrations etc. in Illustrator to i.e PDF, it changes the colors when opening the PDF.
It becomes much more matte and I cannot for the life of me, figure out why this is happening.
I created the illustration using CMYK and I didn't change any color spacing etc in the export.
Here is how it looks in Illustrator: (Colorful and basically how I want it to look)

Here is how the PDF looks: (All matte and boring looking).

And here is my export settings:




Lastly, I apologize for the long post, but I felt like the pictures explained better than words would.
I hope someone can tell me where I go wrong.
Btw, I have tried changing the "Profile Inclusion Policy" to "Don't Include Profiles".
Thank you in advance.
