  Our main result states that every fixed-point free continuous self-map of
${\mathbb R}^{n}$ is colorable. This result can be re-formulated as follows: A
continuous map $f: {\mathbb R}^{n}\to {\mathbb R}^{n}$ is fixed-point free iff
$\widetilde f: \beta {\mathbb R}^{n}\to \beta {\mathbb R}^{n}$ is fixed-point
free. We also obtain a generalization of this fact and present some examples.
