Rainbows

An acrostic with one word filled out due to time. Have a day.

Rain in spring brings colorful surprises
After rain showers of the day, this phenomenon can be seen.
Illusions are of the beautiful seven color kind.
Never try to chase a rainbow
Because they are at an angle to the light.
Older people believe that rainbows are good luck
When you can find a pot of gold at its end.
So just enjoy the experience you just had.
