Obscuritas - Lila

Obscuritas - Darkness. What is darkness? Could it be all and nothing? Black is known to be a shade and not a colour, yet it's the most complete colour of them all since all colours are necessary to produce black. How about Gold then? Gold is an effect caused by the way light is reflected on an object and does not exist independently by the object itself. When looking at gold with high-powered microscopes you'll find reds, yellows and some blues. We know the as the primary colours that makes up the whole colour spectrum. So, is "Obscuritas" the most or the least colourful painting you'll see today?
