Some examples of Σ1 1-universal preorders are presented, in the form of various relations of embeddability between countable coloured total orders. As an application, strengthening a theorem of (Marcone, A. and Rosendal, C.: The Complexity of Continuous Embeddability between Dendrites, J. Symb. Log. 69 (2004), 663–673), the Σ1 1-universality of continuous embeddability for dendrites whose branch points have order 3 is obtained.
