Supplies
- Drawing pencil (HB)
- Hot press watercolor paper (one sheet)
- M. Graham artists’ gouache set
- Brush set (round 2 or 6)
- Porcelain mixing tray

Instructions
- Obtain an HB drawing pencil and one sheet of hot press watercolor paper.
- Draw a painting grid as shown in Figure 1.

- Remove any excess lead by lightly pressing the kneaded eraser over the pencil marks.
- Mix orange in the mixing tray with 50% yellow and 50% red.
- Mix purple in the mixing tray with 50% red and 50% blue.
- Mix green in the mixing tray with 50% yellow and 50% blue.
- Ensure that you have mixed enough of each color in the tray to complete the entire grid.
- Mix each color combination in the mixing tray and paint it into the corresponding square on the grid. For example, in the first row in the first column, paint 100% white. In the first row in the second column, paint a mixture of 50% white and 50% yellow. In the first row in the third column, paint a mixture of 50% white and 50% orange. Continue mixing the colors based on the intersection of each color on the grid.
- Complete the entire board. Use the completed grid as a reference for color mixing options in future projects.
