In a released statement, Samsung has announced that the Blue Topaz version of the Samsung Galaxy S6 and the Green Emerald version of the Samsung Galaxy S6 edge are now available. Samsung's announcement does not mention a specific launch date nor does it state which regions the new colors are available in. Both models are currently available in White Pearl, Black Sapphire and Gold Platinum.
The Blue Topaz and Green Emerald colors were announced back at MWC when Samsung first unveiled its new flagship models. Talking about the Blue Topaz color, British Psychologist Dr. Donna Dawson said that, "People who opt for Samsung’s Blue Topaz Galaxy S6 are likely to be more self-confident, fastidious, discriminating, sensitive, exacting, and intuitive. The ‘brightness’ of the color tends to attract more people who are both self-assured and know what they like."
Dawson adds that "People who choose Green as their preferred color will tend to be balanced, loyal, hard-working, honest, benevolent and concerned for others. They may aspire to be good citizens with a highly-developed moral sense and a desire for simplicity. ‘Green’ also represents new life and new beginnings, and often inspires ‘hope’ and renewed vitality and energy in people, conveying friendliness and a connection to others."
