2. Chroma scale. Materials: 9" x 12" drawing paper, poster paints, brushes, mixing palette, water container, newspaper to cover work area, found objects to match colors.

Chroma is the brightness or the dullness of a color. Change the chroma of a color by adding small amounts of its compliment (the color opposite on the color wheel). Use only two colors which are compliments, i.e. Red and green, or blue and orange, or yellow and purple. Use your mixing palette to mix your colors. Start with pure color on both ends of your scale. For the middle color add equal amounts of the two pure colors. To each pure color add small amounts of the compliment so that you have five steps on either side of the middle color. After mixing the colors and painting swatches of them, be creative in their arrangement on a 9" x 12" sheet of drawing paper.

Format: chroma scale on 9" x 12" drawing paper creatively shaped and arranged. Name printed neatly and ledgibly in lower left corner with date. Include a border drawn with black pen 1/2" from the edge of the paper.

3. Value scale: Materials: 9" x 12" drawing paper, poster paints, brushes, mixing palette, water container, newspaper to cover work area, found objects to match colors.

Value is the darkness or the lightness of a color. Change the value of a color by adding small amounts of white or black to it. Use only one color plus black and white. Use your mixing palette to mix your colors. Start with pure color in the middle of your scale. Add black to form the colors on one side and white to form the colors on the other side. Do five steps on either side of the middle color. After mixing the colors and painting swatches of them, be creative in their arrangement on a 9" x 12" sheet of drawing paper.
