The picture was at first taken from <a href="https://pl.wikipedia.org/wiki/Grafika:Godlo_Polski_z_DzU.jpg" class="extiw" title="pl:Grafika:Godlo Polski z DzU.jpg">pl:Grafika:Godlo Polski z DzU.jpg</a> and then cut down. The red background was calculated in accordance to the official specifications found in attachment no. 2 of "Coat of arms, Colours and Anthem of the Republic of Poland, and State Seals Act". This data was expressed in CIE xyY color space (which is a two-dimensional projection of the <a href="https://en.wikipedia.org/wiki/CIE_1931_color_space" class="extiw" title="en:CIE 1931 color space">CIE XYZ color space</a> plus brightness), where x and y are chromaticity (colour) coordinates and Y is luminance (brightness), and a permissible deviation range expressed as delta E in CIE 1976 (L* u* v*), and was set to x=0.570, y=0.305, Y=16.0, E=8.0. The calculation used the sRGB profile and assumed the white point colour temperature at 6500K.
