pawn Код:

#define COLOR_RED 0xFF0000AA

Lets take this as an example.

If you're going to use such a thing as a HEX code you need to convert it as well, so the following color would look like this:

pawn Код:

#define COL_RED "{FF0000}"

Now let's move on to the usage as well:

pawn Код:

public OnPlayerText(playerid, text[])
{
new string[50];
new pName[MAX_PLAYER_NAME];
GetPlayerName(playerid, pName, 24);
format(string,sizeof(string),"My name is "#COL_RED"%s",pName);
SendClientMessageToAll(-1, string);

I hope that I helped you!.
