Colors using Adafruit_ST7735.h

i'm trying fill in gaps colors.  i've started trying save orange.  see in adafruit_st7735.h ,for lcd display, colors defined 0xabcd.  when colors online see 6 digit hex 0xabcdef.  missing?  how define colors using 4 digit hex, seen in adafruit_st7735.h file?

code: [select]

// color definitions
#define st7735_black   0x0000
#define st7735_blue    0xf800
#define st7735_red     0x001f
#define st7735_orange  0x00aa  //test creating color
#define st7735_green   0x07e0
#define st7735_cyan    0xffe0
#define st7735_magenta 0xf81f
#define st7735_yellow  0x07ff
#define st7735_white   0xffff

there color565(r, g, b) method.
you can write equivalent macro.
