Purple is royal here! Everything is purple, purple face, eyes, background, lips...the whole image is smoking in dry shades of pastel purple. 
The painting is filled with the emotions, and mixed with expressionistic colors it demonstrates the one feeling ‘’right before the waterfalls’’  
Technique used in this work is the old-fashioned dry pastel, typical for the artists, which prefers the most this type of colors. What better than dry pastels to be used for the explosion of the colors?
