Brown is the colour of earth, soil, stone and wood.  It is nature's colour.  The colour brown is believed to affect the mind and body by creating feelings of wholesomeness, stability and peace.  Brown also provides feelings of organization, history and connection.   

To be knowlegeable means to have insight and clear understanding.  

I was completely grounded when I came across some indiginous wooden carvings depicting the history of the land I was standing on.  The warm browns of the wooden carving did give me a sense of peace.  The history of the carving, its meaning and its craftsmanship added to my knowledge base.

Can you find something brown today that shows a sense of history?
