Why not have each card as a unique number, and decide from that number what suit it is? The suit defines the color, so that solves both problems.

Code:
#include <stdio.h>

enum suit_t
{
        // Arranged in this order to get black/red/black/red.
        SUIT_CLUB=0,    // 0 & 1 == 0.  Black.
        SUIT_HEART=1,   // 1 & 1 == 1.  Red.
        SUIT_SPADE=2,   // 2 & 1 == 0.  Black.
        SUIT_DIAMOND=3  // 3 & 1 == 1.  Red.
};

enum card_t
{
        CARD_MIN=0, CARD_MAX=52,

        // Cards are numbered as 0, 4, 8, 12, etc.  The first 2 bits decide the suit.
        CARD_ACE=(0<<2),      CARD_2=(1<<2),
        CARD_3=(2<<2),          CARD_4=(3<<2),
        CARD_5=(4<<2),          CARD_6=(5<<2),
        CARD_7=(6<<2),          CARD_8=(7<<2),
        CARD_9=(8<<2),          CARD_10=(9<<2),
        CARD_JACK=(10<<2),      CARD_QUEEN=(11<<2),
        CARD_KING=(12<<2)
};

const char const *cardnames[]={
        "Ace", "Two", "Three", "Four", "Five", "Six", "Seven",
        "Eight", "Nine", "Ten", "Jack", "Queen", "King", NULL };

const char const *colornames[]={ "Black", "Red", NULL };
const char const *suitnames[]={"Clubs", "Hearts", "Spades", "Diamonds", NULL };

#define CARD_NAMESTR(X)         (cardnames[(X)>>2])
#define CARD_SUITSTR(X)         (suitnames[(X)&SUIT_DIAMOND])
#define CARD_COLORSTR(X)        (colornames[((X)&1)])

int main(void)
{
        int card;

        for(card=CARD_MIN; card < CARD_MAX; card++)
        {
                printf("card %d is the %s of %s, and is %s\n", card,
                        CARD_NAMESTR(card), CARD_SUITSTR(card),
                        CARD_COLORSTR(card));
        }
}

Code:
card 0 is the Ace of Clubs, and is Black
card 1 is the Ace of Hearts, and is Red
card 2 is the Ace of Spades, and is Black
card 3 is the Ace of Diamonds, and is Red
card 4 is the Two of Clubs, and is Black
card 5 is the Two of Hearts, and is Red
card 6 is the Two of Spades, and is Black
card 7 is the Two of Diamonds, and is Red
...
card 44 is the Queen of Clubs, and is Black
card 45 is the Queen of Hearts, and is Red
card 46 is the Queen of Spades, and is Black
card 47 is the Queen of Diamonds, and is Red
card 48 is the King of Clubs, and is Black
card 49 is the King of Hearts, and is Red
card 50 is the King of Spades, and is Black
card 51 is the King of Diamonds, and is Red

secolor.conf

secolor.conf(5) 						File Formats Manual						   secolor.conf(5)

NAME

       secolor.conf - The SELinux color configuration file.

DESCRIPTION

       This  optional  file controls the color to be associated to the context components associated to the raw context passed by selinux_raw_con-
       text_to_color(3), when context related information is to be displayed in color by an SELinux-aware application.

       selinux_raw_context_to_color(3) obtains this color information from the	active	policy	secolor.conf  file  as	returned  by  selinux_col-
       ors_path(3).

FILE FORMAT

       The file format is as follows:
	      color color_name = #color_mask
	      [...]

	      context_component string = fg_color_name bg_color_name
	      [...]

       Where:
       color
	      The color keyword. Each color entry is on a new line.
       color_name
	      A single word name for the color (e.g. red).
       color_mask
	      A color mask starting with a hash (#) that describes the hexadecimal RGB colors with black being #000000 and white being #ffffff.
       context_component
	      The context component name that must be one of the following:
		     user, role, type or range
	      Each context_component string ...  entry is on a new line.
       string
	      This is the context_component string that will be matched with the raw context component passed by selinux_raw_context_to_color(3).
	      A wildcard '*' may be used to match any undefined string for the user, role and type context_component entries only.

       fg_color_name
	      The color_name string that will be used as the foreground color.	A color_mask may also be used.
       bg_color_name
	      The color_name string that will be used as the background color.	A color_mask may also be used.

EXAMPLES

       Example 1 entries are:
	      color black  = #000000
	      color green  = #008000
	      color yellow = #ffff00
	      color blue   = #0000ff
	      color white  = #ffffff
	      color red    = #ff0000
	      color orange = #ffa500
	      color tan    = #D2B48C

	      user * = black white
	      role * = white black
	      type * = tan orange
	      range s0-s0:c0.c1023 = black green
	      range s1-s1:c0.c1023 = white green
	      range s3-s3:c0.c1023 = black tan
	      range s5-s5:c0.c1023 = white blue
	      range s7-s7:c0.c1023 = black red
	      range s9-s9:c0.c1023 = black orange
	      range s15:c0.c1023   = black yellow

       Example 2 entries are:
	      color black  = #000000
	      color green  = #008000
	      color yellow = #ffff00
	      color blue   = #0000ff
	      color white  = #ffffff
	      color red    = #ff0000
	      color orange = #ffa500
	      color tan    = #d2b48c

	      user unconfined_u = #ff0000 green
	      role unconfined_r = red #ffffff
	      type unconfined_t = red orange
	      user user_u	= black green
	      role user_r	= white black
	      type user_t	= tan red
	      user xguest_u	= black yellow
	      role xguest_r	= black red
	      type xguest_t	= black green
	      user sysadm_u	= white black
	      range s0:c0.c1023 = black white
	      user *		= black white
	      role *		= black white
	      type *		= black white
