Orange Slices Green Plate on Lavender

I really like this square green plate. (You may have noticed I've used it before.)  It is so vibrant and really sets off the orange slices.  This painting is done in a triad of secondary colors- orange, purple, and green.  Because the three colors are high key (light in  value) they harmonize rather than clash.  The purple covers more area of the canvas, but the orange is more saturated (intense) and thus the dominant color.
