The second logo adopted a blue triangle (with the bottom point missing) and a red triangle superimposed upon it, enclosed by a circle; this was meant to evoke a vertically-displayed national flag (the white being formed by the negative space between the two triangles' tips). In the mid-1970s, a third logo, which removed the circle and simplified the shapes, was introduced. The typeface used in the third logo was later applied to the second logo, which remained the official PAL logo until 1986 when it would be replaced by the current logo.
