Really cool!!... how did you decide to put the purple colors for the cast shadow, or what are the factors to consider in order to make the shadow believable with all the light sources affecting the enviroment????
hi there. thanks for your interest. choosing colors during a pleine aire session is a lot about seeing more so than inventing. when u actually observe how vibrant light and color behave in nature, it feels natural to make some of these color decisions. it's something that has to be experienced in the field. if i was simply working at home from reference, i doubt that i would ever think to use colors in the same way that i do when im out painting. the colors that i found on this day are perhaps exagerrated versions of what my eyes perceive... but even still, they end up making a readable, and hopefully convincing imprint on the viewer. after that, it's about adjusting and balancing different areas of the piece till it resolves as a whole image. hope that illuminates the thing that u were asking about.
