We consider the question of the computational complexity of coloring perfect graphs with some precolored vertices. It is well known that a perfect graph can be colored optimally in polynomial time. Our results give a sharp border between the polynomial and NP-complete instances, when precolored vert

## Abstract We derive decomposition theorems for __P__~6~, __K__~1~ + __P__~4~βfree graphs, __P__~5~, __K__~1~ + __P__~4~βfree graphs and __P__~5~, __K__~1~ + __C__~4~βfree graphs, and deduce linear Οβbinding functions for these classes of graphs (here, __P__~__n__~ (__C__~__n__~) denotes the path
