Wrote my own function.

pawn Код:

stock ColorToEmbed(const color[]) {
    new finalclr[7];
    format(finalclr, sizeof finalclr, "%s", color[2]);
    return finalclr;
}

CMD:embed(playerid, params) {
    new str[128], col[7];
    col = ColorToEmbed("0xFFFFFFFF");
    format(str, sizeof str, "Hi {%s}there.", col);
    SendClientMessage(playerid, 0xFF0000FF, str);
    return 1;
}

You need to input your color as a string into ColorToEmbed and it will return a color string without 0x and the last 2 characters. Works like charm.
