Colour hopping

Some months back
everything you touched was aed (red in color)

One month back
everything you touched was bloo (blue in color)

One fortnight back
anything could be any (aed, bloo, yello, geen)

One week back, 

Sometimes,
aeds are indeed reds
bloos are indeed blues
yellos are yellows and
geens are greens
At other times,
aeds are bloos and

bloos are aeds

but its not too far

when 

aeds will always be reds and

bloos will always be blues
