Sanguine (heraldry)
From Infogalactic: the planetary knowledge core
Sanguine (/ˈsæŋɡwɪn/) is a stain, or non-standard tincture in heraldry, of a blood-red colour. In the past it was sometimes taken to be equivalent to murrey, but they are now considered two distinct tinctures. It is a brownish red, the colour of arterial blood.[1]

The Coat of arms of Latvia feature a ribbon sanguine.
Roundels of sanguine are referred to as guzes, from the Turkish göz, meaning an eye.
