The Colour Theory (College Work)

Colour Theory, an explanation of what happens when colours are mixed together to create another. These sorts of thoughts were first found around the 1400's by two artists, who happened to have written notes of these studies; Leon Battista Alberti (Dated; 1435) and Leonardo da Vinci (Dated; 1490). This was properly examined until dear Isaac Newton created an explanation of Primary Colours. Creating this possibility and reliable source, Newton managed to express a new world in both artistic standards and science all together.
During those days of the 1700's, confusion took place when they realized the same attribute to light generated colours, or Additive colours, reflecting off each other was not merely the same when paints or inks, or Subtractive Colours, were mixed into the same sort of state. Later on down the time line other general problems started to occur, such as understanding of light and dark, shadows and possible anatomy of colour usage and unseen blends of colours. It wasn't until the 19th Century that we finally understood Colour's properties, but scientific evidence disagreed on the facts, and demanded more research. 
Scientific discovery explains how light and darkness really effects the tone or texture of a certain colour which reflects into our eyes. During the 1900's, colour coding was introduced to keep track of these certain tones of colours to refer to the exact colour of what is needed. Programs or systems are transcribed to use these coding systems in today's software (HTML Pantone, Pantone in general, Truematch, etc).
