The country had – like all the other crown lands of the Austrian crown – its own colours (Landesfarben), which were used amongst others on horizontally two- or three-striped flags. The colours (Landesfarben) were very often taken from the respective coat of arms of the country or were supplemented by another colour, which not appears in the coat of arms, or they went back to older models of the coat of arms (e.g. Carniola). Officially, the colours had never been regulated or stipulated, so that their sequence varied in practice or even the colors deviated. The Austrian heraldist Hugo Gerard Ströhl (1851–1919) was probably the first to take care of it and asked for the colors (Landesfarben) on the flags at the respective state authorities around 1890 and compiled them. Austrian Silesia used as colours of the country a flag which showed two horizontal stripes in gold and black. The colours descend from the coat of arms of Silesia: black eagle upon gold. The colours appear heraldical wrong – because gold is above – probably to make possible a differentiation to the then Austrian national flag.
The coat of arms of Silesia shows a crowned, golden armed, black eagle on golden ground. The eagle is covered with a silver crescent ending in clover stems, which has a cross in the middle. The Silesian eagle appeared still until 1960 in the coat of arms of Czechoslovakia. Since 1992 appears the eagle again in the coat of arms of Czechia.
The historical map shows Prussian Silesia between 1806 and 1815 as bright red area. The yellow areas in the Northeast have been ceded by Saxony to Prussia in 1815 and became connected to Silesia. Austrian Silesia (1742-1918) appears in a dark yellow outline. In the year 1919 Prussian Silesia became divided into two provinces, Upper Silesia (bright red outline) and Lower Silesia (bright blue outline).
