(Urgent) Colors Washed Out after exporting to PDF
Hello,
My document in Illustrator, is original in RGB color mode, because the purpose of the project is not for printing. But when I exported it to PDF, I found that the colors were a bit "washed out", colors were not as sharp as the color shown on the Illustrator document. When I tried to export it in JPG, it shows the exactly same colors as the original document.
My project will due on Sunday, and I was supposed to submit the PDF file. So I hope I can find the solution as soon as possible. Thank you.

Thank you for the explaination, I used "save as" as my method. So what should I do right now?
