According to Details Enclosed: Who or What am I?

Adorned mostly in blue & white I frequently bare an array of colors going to & fro

Though I spend my day happily it can get clouded with grey which brings tears to my eyes

The white in my vastness is full of everyday beauty but can only be seen with the eyes of beauty

The blue that over powers all can be seen as an unending ocean which covers every corner of the earth

My belly is powerfully filled twice per day; therefore even in my darkest hours I am happily shinning with delight

I am so overjoyed with your company that I Promise never to leave you; though far too often you never notice

Hey I’ll try not to eat too much this summer don’t want to make you too uncomfortable ing

Oh How I love watching over you

Please tell the line that gave you your answer

Who or What am I??

God’s Agopey Love & Blessings!
