Grade 3 Artists practiced mixing color values, then using the values to show distance in a landscape painting. First, they drew five simple pencil lines across the page to represent sections of the land, seen from above. They began mixing values by starting with white, then mixing very small drops of color into it on a painter's palette. They added more and more drops for each darker tone. They painted a sections of the color's hue, or pure color. Then they tried creating shades by starting with the color and adding very small drops of black for the bottom or closest sections. Their finished work made a beautiful hallway display!
