I think I see the decades through colours: the 1990s was yellow and the 2000s white
However, I am still undecided about the 2010s..
I am sure though that this colouring changes the arithmetic of time:
As the calendar units are based on visual entities and not in numbers the 1990s split into the 2000s and the 2000s into 2010s
In this sense I think we are still somehow within the whiteness of the 2000 heading towards a new circle of colour which is not yet fully perceptible
but is probably light blue...
