How to localize a string with colors and variables in bash

I have some colors defined out of the function and also a function where I want to use these colors and localize the string where I use them:

. gettext.sh

(...)

CC="\033[1;36m"
WC="\033[1;97m"
NC="\033[0m"

(...)

init() {
    pkg="$1"
    echo -e "Package ${WC}${pkg}${NC} ${CC}not found${NC}."
}

(...)

I have refactorized the function init to:

init() {
    eval_gettext "Package \${WC}\${pkg}\${NC} \${CC}not found\${NC}."; echo -e
}

When I try to get the msgids I can see the following:

#, sh-format
msgid "Package ${WC}${pkg}${NC} ${CC}not found${NC}."
msgstr ""

But when I execute the script, then I see this message:

/usr/bin/gettext.sh: line 88: export: `WC
pkg
NC
CC
NC': not a valid identifier
Package  not found.

In fact, shellcheck is advising that the color variables are not being used...

How could I refactorize it to work?

Edit:

This code works:

printf "$(gettext "Package %b%s %bnot found%b.\n")" "$WC" "$pkg" "$CC" "$NC"

But It has the problem that a command would not be executed in the fist param of the printf

Try this way:

WC="\033[1;35m"

Sorry, I don't see the difference
