In Tibetan Buddhism, Amitābha is red in color (red being the color of love, compassion, and emotional energy). His direction is west and so he is envisioned as the (red) setting sun. He is seen as the supreme power and energy of nature, cast on an earthly plain, accessible to all sentient beings. For this reason he is considered one of the most popular of all Dhyāni Buddhas.

Amitabha Buddha emanates ruby red light. Red symbolises love and compassion. Like the setting sun, his radiant form warms and pacifies the hearts of all who gaze at him. As head of the Lotus family, he represents gentleness and openness. This reflects his boundless compassion and receptivity enabling one to feel accepted and protected.
