SWMBO instructed me to grow some peppers, labeled 'green' in the hope they
would turn yellow in time, well, time is passing and they show no intention
of turning yellow, so can I expect them to turn yellow or am I wasting my
time?

Green is not the fully ripe colour of peppers, but they are more likely
to turn red (via brown) which is the natural sequence.

To get yellow or orange ones, you will need a yellow or orange variety.
