1. The law is not to be hoodwinked by colorable pretences. 2. There is not even a colorable political reason. 3. The same rule applies to some nonplanar surfaces which are not four-colorable . 4. Infringement cases do not require actual imitation; only a colorable one, likely to confuse the public. 5. Axenovich proved that all outerplanar triangulations with more than three vertices and without separating triangles are interval colorable . 6. In this case, a link is 3-colorable if it has more than three 3-colorings. 7. Indeed, even Max Independent Set on 3-regular 3-edge-colorable graphs is APX-complete. 8. This really does not hold in general, as there are maps in nonplanar surfaces which are not four-colorable . 9. Spartaz has added colorable post-ban sock allegations . talk ) 23 : 10, 9 February 2016 ( UTC) 10. A graph that can be assigned a ( proper )-edge-coloring is said to be-edge-colorable .
