When you add stickers atop paper of nearly the same color then you really want to do something to make them stand out. I often outline stickers with a journaling pen to give the appearance of dimension but using Glossy Accents by Ranger can actually give you that dimension. I don’t know of any other product at this time to give the same result.
On this “Superfun!” page, which is the closing page of the album commemorating my trip to Michigan, I used some deep blue alphabet stickers to make my title atop a polka dot page of nearly the same color. The letters were visible and you could technically feel them in place before I put the Glossy Accents on them. But what a difference!
