My two favorite products for creating quick and easy background papers for collage or altered books. Both are translucent - not opaque - which I like, because it lets the text or images on the background pages show through.
The first is Pearlescent Liquid Acrylic and the second is Silky crayons by AMOS, or the same product by Elmers called Colorslicks. The Liquid Acrylic is a quick-drying ink that comes in around 20 different beautiful pearlescent colors. The crayons come in tubes of various sizes - some shaped like a marker, others like a glue stick. They have both regular and metallic colors and are watersoluble. They glide onto paper like a lipstick or oil pastel, but quickly dry to the touch - so there is no smudging or mess. Neat color blends can be created by adding water to the page.
