Yellow is the mark of the melancholy and morose. Pink denotes a hopeful, sanguine, enthusiastic, and bright nature. One may consider it to be a less extreme manifestation of a red hand or line. This is the optimal color for any line in a healthy, well-adjusted person. White denotes a lack of interest in the outside world and those with whom the bearer may associate.
White hands are egotistical, consequenting in selfishness and a lack of sympathy for others.
It is also a symbol for general ill-health and weakness. A dark or black line denotes a trait of a person as grave, haughty, distant, and vengeful. When diagnosing the import of a line, color, length, and direction are not enough. Often the manner in which the line is etched into the palm will indicate its overall power. A deeply-cut line strengthens the influence of the line over other traits.
