my favourite colour is purple, Whats yours?
I love blue, but purple is also nice, since its an intermediate between blue and red.
True, I just love the varying shades, especially the way they express themselves in flowers
Then you might not be surprised to know that purple is the color most often associated with royalty, magic, mystery and piety!
That is surprising! is there any paticular reason for this?
Yes actually, purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire. Pretty neat, huh?!
That is very interesting, what time period was that in? 
During the Byzantine era, which was centuries ago. Even Similarly in Japan, the color is traditionally associated with the Emperor and aristocracy! 
Wow, are there any other colours commonly associated with royalty?
The complementary color of purple is yellow so yellow is the closest we can get to such a royalty color
