Answer 2

More or less like this

#!/usr/bin/env bash

SETCOLOR_SUCCESS="echo -en \\033[1;32m"
SETCOLOR_FAILURE="echo -en \\033[1;31m"
SETCOLOR_WARNING="echo -en \\033[1;33m"
SETCOLOR_NORMAL="echo -en \\033[0;39m"

${SETCOLOR_SUCCESS}
echo "Connected"
${SETCOLOR_NORMAL}

${SETCOLOR_FAILURE}
echo "Not connected"
${SETCOLOR_NORMAL}

${SETCOLOR_WARNING}
echo "Some warning"
${SETCOLOR_NORMAL}
