Indigo
A blue close to black — the colour of inward depth and of night that has not yet finished.
Indigo in a dream is the dream's image of a blue so deep it is on the edge of night. Indigo is the colour of the hour before dawn, of careful old workwear, of thought that has gone past the easy answers. The dream brings indigo when something in your life — a long work, a private knowing, a stretch of grief — is being held in a register too quiet for daylight. An indigo cloth worn close to the skin is the dream telling you the deep work is being kept honest. An indigo fading toward grey is the dream noting that the depth you used to carry is leaving, and the colour of your interior is going thin.
