The aim of this paper is to present the results of a questionnaire the purpose of which was to investigate whether the primary basic colour terms in Polish (i.e. the equivalents of English white, black, red, green, yellow and blue) have the same reference-points in four regions of Poland. It appears that the reference-points are different for 'niebieski' (blue): in Central and Southern Poland it is associated mainly with the sky, whereas the inhabitants of Northern Poland associate it with the sky and water, just like speakers of English and Swedish. The vicinity of the Baltic Sea is undoubtedly the factor which influences this treatment of 'niebieski' by the inhabitants of Northern Poland.
