I am not sure about the color Purple. Do you like it?
Yeah I guess I like it, It's a cross between blue and red, so if you like either of those, you should like purple!
I like those but still not sure about purple.  Any idea what is the symbolic meaning of this color?
Well purple was always a symbol of royalty in the past.  In fact, the Byzantine Empire made it the official imperial color worn by the rulers.
And what about today?  I believe it is used by catholic clergy, am I right?
Oh yes, even in the past the Holy Roman Empire and the Roman Catholic bishops wore purple to symbolize their ruling status.
And don't know I 've heard that eaither purple or lila are used as a mourning color, like black,  but I don't remember anyone wearing purple at a funeral.
Wearing black as a sign of mourning is a very common practice followed in many countries, however I can't say that I've heard of purple being used as a color for mourning.
