yes "shlon" is used in many countries! and when a person want to be silly they answer when asked "shlonak" >> "a7mar" or whatever colour comes up to their mind, but it is not the true meaning of it.. shlon+ak means how are you
sho+lonak means what's your colour
however they are pronounced the same way!~
The hours of pain have yielded good,
Which prosperous days refused;
As herbs, though scentless when entire,
Spread fragrance when they’re bruised.
