Warm & Cool Colors is part of what Artist call Color Theory. Awesome Artist . com has wonderful information on this.
We extended are first Color Wheel mixing activity by painting the color wheel. I only gave my Beloveds the three primary colors and they were responsible to create the secondary and tertiary colors.
Then we use this Color Scheme sheet.
After we studied Color Theory, we created these warm and cool art pieces. They first started by drawing stripes on their paper the width of a ruler horizontal then vertically. They could either draw the lines light or erase the lines so that it would not show through the water color. They each drew a simple design that they could paint with either warm or cool colors, making the background the opposite color scheme.
