sky blue

sky blue
different blue
at different hours

sometimes
pale
as the sun begins to shine
almost grey

an old man's
pale blue eyes

as the oranges, golds and reds
fade away
white, silver, grey, blue

sometimes lighter
than the blue in the flag

other times
bluer, pure without even
a hint of cloud

then the sky
becomes coral
orange, silver, gold
sooty grey

until
the darkest blue
darker than the deep sea

so what is sky blue?
