Yes there is varigated hand quilting thread. You can even buy it at Wal Mart or quilt shops. I think it breaks a little easier than regular quilting thread but just use shorter lengths of thread. I like the look, in colorful quilts, it blends in plain colors it add a little spark and is beautiful on the back.
Attached pic of one,but maybe you can't tell the colors in the quilting thread. Ruth
