There is a wide selection of colors here, and a few sheets of each color.  The yellow doesn't bleed as much as I prefer - I'm one for a bright sunshine yellow - but the other colors do just fine.  Plenty of color, and you don't need a large piece to create with.  I started by cutting 1" x 2" strips of the whole pack, just one small corner, and had enough color for 3 pieces of art.  I just spritzed my watercolor paper generously (cardstock works too) and plopped the tissue pieces down, scrunched some, left others flat.  I could move them around and spread the color in other places.  All in all, a very satisfying way to have fun.  They WILL stain your fingers, but not permanently.  Easier to remove than alcohol ink... not for small children unless you want carpeting colored.  I don't know if it will come out of clothing, either.
