Ripe 'kalina' is definetly red in color. I think sometimes ' red kalina' has a symbolic meaning of 'blood':in "The Brothers Karamazov" when Mitya is in the garden of his father before the murder he mentions 'how red are the berries'. A very popular movie by Vasolii Shukshin is also entitled "Kalina krasnaya". Irena Ustinova
