Hi I'm started my blog at the beginning today with researching colour!  Apparently Sir Isaac Newton invented the first colour wheel back in the 17th century.  Of course colour existed long before this and is a seen as a very emotional 'element of art'.  We seem to have a natural and conditioned awareness of colour and I just know I'm going to enjoy researching more about this topic.
The above is an image of Johannes Itten's Color Star. 
Johannes Itten has long been considered the definitive colour theorist of the 2oth century.  His books on colour theory and application are standard throughout the world.  Such as The Art Of Color.  His ‘Colour Star’ helps designers explore a myriad of harmonious colour.  Consisting of eight stencil-like disks that can be placed over ltten's colour wheel to compare cool and warm values, complementary colours, and different hues and intensities.
It's very strange sitting in a dark computer room typing this, the only colour seems to come from the bright screens!  Lynne has been great showing me how to do all these things today...very sharp learning curve! thanks Lynne.  Now I will see if this works!
