As Junio pointed out, the colon here is not syntactic, but from the
original object name you gave it. But here...

...it is missing. Did you mean to omit it from the command-line?

I suspect that is cut-and-paste something.  I see:

    $ git show 04050d37b1676ba8da277be1902513049b45413a: | head -n1
    tree 04050d37b1676ba8da277be1902513049b45413a:
    $ git show 04050d37b1676ba8da277be1902513049b45413a | head -n1
    tree 04050d37b1676ba8da277be1902513049b45413a

which is expected.

It indeed becomes confusing when you give "<treeish>:" from the
command line, as it looks as if there is conceptually a list of tree
contents that is shown like so:

    tree tree1:
    contents of tree1

    tree tree2:
    contents of tree2
    ...

and we are showing only the first one.  If the original input were
given as "<treeish>^{tree}", there is no confusion.
