    • getClosestNamedColor

      public static String getClosestNamedColor(Integer hexColor)
      Returns the named color that is closest to the given hex code color value.

      Only the first 6 bytes of hexColor are taken into account. That is two bytes for each red, blue, and green component.

      Parameters:
      hexColor - the Integer hex color value of the named color to return
      Returns:
      the named color that is closest to the given hexString color

      Returns the named color that is closest to the given color.
      Parameters:
      color - the color to find the closest named color for
