Is there a colored equivalent to puzzle coat/modpodge?

What should I use to color (visually, not sonically!) a paper cone? I want to add a little flare to my NSB array once it's constructed. Since i'm going to puzzle coat them anyway, I thought I would color them as well. What could I use that wont adversely effect the cone mechanically and sonically? I was thinking a color coat of maybe acrylic paint, and puzzle coat on top of that.
