Pearl white
A white with depth — the inner colour of something made slowly by irritation.
Pearl white in a dream is the dream's image of a white that holds depth — the white of the inside of the shell, made slowly around a piece of grit. Pearl is not pure; it is the result of a wound coated over and over until the coating itself becomes beautiful. The dream brings the colour when something in your life — a piece of grace, a personal style, an outlook — has been formed by long, patient work around an original irritation. A pearl held in the palm is the dream affirming that the coating has produced something worth carrying. A pearl cracked, showing the grit at the centre, is the dream noting that the original wound is still in there, and the covering has reached the limit of what it can hide.
