Solution by Jaihind Singh.


Blue or Red, the moons are 2
May be twins that will do
It happens the full moon squeezes in blue
A blue moon can also mean that’s untrue
They are on orbit in a mist,
They are now 2
They can rule life and feelings
Both reflect the light of the sun
A blessing boon from the moon
