In winter I look for stimulating subjects to resent in class, and we have covered many over the years. To be honest, if it appeals to me I assume it will appeal to my students:)
When you go to ski village centers where there are art stores (like Sutton or Mont Tremblant, for example) you will often find therein lovely, colourful village scenes. These paintings arise from a tradition set in the early 1900s. Group of seven artists Lawren Harris and A.Y. Jackson were among the painters who developed this almost graphic style of painting. Modern painters take the colourization even further.
To encourage a colourist approach I will suggest creating the drawing in conté, 'fixing' the drawing using acrylic medium, and then removing the original from view and making your own colour choices. I will also encourage adapting parts from several examples I have printed out, or just build your own happy winter village. Can't wait to see what everyone accomplishes - always amazing!
