Thank you for quick reponse. colorstack is ok now.

BTW, I have found a strange behavior of node.unset_attribute.
On compiling tex file like this:

callback.register("pre_linebreak_filter", function(head)
    for curr in node.traverse(head) do
        if curr.id == 10 then % glue
    for curr in node.traverse(head) do
        print(node.type(curr.id), node.has_attribute(curr,100))
\attribute 100 1

messages on the terminal are:

whatsit	nil
hlist	nil
glyph	nil
penalty	nil
glue	1

Why all nodes except glue have lost their attribute,
which is quite contrary to what I expected?
