This lesson can also be applied to create 2D and 3D works in all media. It can be used to slightly abstract works through choice of color and shape or to create works that are completely non-objective.
I have used this approach for about 20 years now, and formalized my information in the book, "The Emotional Color Wheel" (Book is at the bottom of that link) As well as the posters here. But the above sample will be enough to help you without having to purchase anything. A direct link to the free sample is HERE.
I will share with you 3 different approaches I have used.
Family with Shapes and Colors: Students list 8 members of their family and write 5 descriptive words about each (positive and negative if need be) I let them know they can write in code if they want to keep their feelings a secret. After exploring the emotional values of colors and shapes, students create symbolic shapes, lines, and colors for each family member, and make a composition to represent their family. They can organize shapes by how well people get along with each other and the colors between shapes can show how they feel about each other. Here are some samples from my classroom:
Inside the student's shape, they use colors, shapes, lines, etc. to express how they feel about themselves. On the outside they use the same art elements to illustrate assumptions people make about them. This becomes a project that focuses on inside-vs-outside perceptions. It is often a very therapeutic and revealing assignment.
A: (Specific and Personal)
I used red to express my anger about how my parents reacted to me when I revealed a secret to them. I trusted them but I feel like they broke my trust and I can not be as truthful to them anymore.
I used yellow to represent my happiness at overcoming a great obstacle in my life. My family was very supportive and this helped me get through it.
B: (Personal but non-specific)
I used red because I have a temper sometimes and lose control.
I used blue to show that I am a relaxed person who does not get upset easily.
C: (Non-symbolic but connected)
I used pink 'cause I have a pink bedroom.
I used green because the car I want is green.
D: (Not symbolic, not connected)
I used purple, because I like it.
