Assuming your terminal supports ANSI colors, it is quite easy. You just need to add certain echo statements to achieve certain colors.

The syntax is: echo "^[[#m<text>"

Where the the "^[" character is produced by hitting ctrl-v and then escape and # is substituted with a number depending on the effect you want the second "[" and the "m" are literal characters. Here's an excerpt from some C code listing the various colors (because I'm too lazy to retype it in a different format):

Code:
/* foreground colors */
#define AFC_BLACK           30
#define AFC_RED             31
#define AFC_GREEN           32
#define AFC_YELLOW          33
#define AFC_BLUE            34
#define AFC_MAGENTA         35
#define AFC_CYAN            36
#define AFC_WHITE           37

/* ansi background colors */
#define ABC_BLACK           40
#define ABC_RED             41
#define ABC_GREEN           42
#define ABC_YELLOW          43
#define ABC_BLUE            44
#define ABC_MAGENTA         45
#define ABC_CYAN            46
#define ABC_WHITE           47


/* ansi modes */
#define AM_NORMAL               0         
#define AM_BOLD                 1
#define AM_LOWINTESITY          2
#define AM_ITALIC               3
#define AM_UNDERLINE            4
#define AM_BLINK                5
#define AM_RAPIDBLINK           6
#define AM_REVERSE              7
#define AM_INVISIBLE            8

You can combine the modes, so to print the word "hello" in yellow text on a blue background and then return to normal you would use:

echo "^[[33m^[[44mhello^[[0m"
