According to Chapter I, Article 28, paragraph 2 of the Constitution, the national colours of Poland are white and red.<ref name="const" /> The Coat of Arms Act, Article 4, further specifies that the colours are white and red in two horizontal, parallel stripes of equal width, of which the top one is white and the bottom one is red.<ref name="act" /> If the colours are displayed vertically, the white stripe is placed on the left from the onlooker's viewpoint. Attachment no. 2 to the Act shows the national colours in both horizontal and vertical alignment, as well as the official shades of both colours expressed as coordinates in the [[CIE xyY]] (CIE 1931) [[color space|colour space]] with the tolerated [[color difference|colour difference]]s (ΔE) specified in the CIE 1976 (''L''*, ''u''*, ''v''*) colour space ([[CIELUV]]).<ref name="act" />
