Colours of the rainbow always making me think about how the beautiful is world we are living.
I'm truly amazed of numbers of colours and tints in natural world.

But do you know there is only seven colors of the rainbow?
czerwony - red,
pomarańczowy - orange,
żółty - yellow,
zielony - green,
niebieski - blue ,
