Colours

 

2012: 225th Birth Anniversary - Joseph on Fraunhofer
Jospeph Faunhfer was the inventor of the spectroscope and in 1814 discovered the optical absorption solar spectrum. Today the lines are named after him - Fraunhofer lines.  The stamp is his spectrum of the sun.
2016: Northern Lights
We are going through a period of high solar activity
so it is a good opportunity to see the northern lights. So far I have have missed them all!  I wonder what the Northern Lights look like to other fauna

2015: Flowers - Festive Bouquet
who perceive ultraviolet light and see a very different world of colour.  Interestingly no two species see the world in the same colours.  Bees perceive ultraviolet light but are as blind to red as humans are to UV light (human eye receptors are sensitive to red)
2003: Post - Rural House Postbox

This spectrum blindness is no impediment to bees when they occasionally decide to set up home in a postbox.  This one is bee free although happily the flowers will not be.

Great Northern Lights stamps. Good interpretation of the theme.

The spectrum stamp is fascinating. I cant stop looking at it! The northern lights are also beautiful!

It certainly has been a year for northern lights. Those Swedish skies are quite spectacular. I am still trying to wrap my head around the solar spectrum (my head that is in no way scientifically inclined!)

The first one is the perfect stamp for today's theme.
The northern lights again... one day I hope to see one!
Oh, and the last postbox is lovely :)
