Have you seen anything unusual in nature lately?

I saw two rainbows in the last week and a half . I used to see them as kid a long time ago but they seemed to stop appearing . I never really thought about why until I saw the rainbows recently and it kind of made me wonder why.I remember seeing rainbows with deep color not faded ones like I see now almost like out of a movie with a pot of gold at the end. I wonder why ?
