Linear highway of four colors
Schematic drawing of a family of four
A blue parrot rides a four-wheeled bicycle
Fingers smoothly press the piano keys
Four multicolored squares on a blue background
Four people who play sports
Four dolphins swim in the ocean
A man in a T-shirt on an island points his finger at the ground
Four soldiers hid from bombs
Four-wing butterfly on a leaf
Four triangles of different colors
Four trees in the snow on a hill
