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. The Crown Land of Istria used as colours of the country a flag which showed three horizontal stripes in gold, red and blue. The colours descend from the coat of arms of Istrien: blue goat-buck with red arms on a blue shield.
The coat of arms of Istria shows a golden goat with red arms on a blue shield. The central image of the coat of arms goes back to the Venetians, who ruled the western part of Istria from the 9th century to 1797. The Austrian heraldist Hugo Gerard Ströhl surrounded the coat of arms ca. 1890 with Apple blossoms, to emphasize the importance of the country as a fruit-growing region. The heraldry of Istria appears since 1992 in one of the five regional scutcheons in the upper part of the coat of arms of Croatia.

The name "Istria" goes back to the Illyrian people of the "Histri" who lived here in antiquity. The name was given by the Romans, who conquered the country in 177 B.C. For them, the Illyrian inhabitants of the peninsula were pirates. Since there are no linguistic bequests of the Histri, you can, if you want, find the Latin word "Histrionia" in the word "Histri", which means "acting". This may have been a reference to the inventive piracy of the Illyrian inhabitants of the peninsula at that time, and not the real name of the people who originally lived here.
