Colours of the seasons

My colour was autumn 
in a fading colour kind of way
as I scrambled for more time
as time slipped away

then my colour was winter
cold bleak and grey
the shortening of daylight
gave more night than day

when my colour was spring
and more light filled the air
I felt for a green time
my happiness was there

but my colour became summer
coming in bright yellow hues
til the landscapes went dry
sun extracted summer dues

now my colour is a rainbow
arching over seasons
casting no shadow
coloured joy without reason
