* JOSEF ALBERS’ “INTERACTION OF COLOR” ("IOC")
COLOR THEORY COURSE
NOTE: The Interaction of Color course offered in the web site is the complete course. Because of time constraints, the most outstanding and important studies have been selected for IHA's Studio Art Course. Consult the "IOC IHA STUDIES CHECKLIST" link for IHA-offered studies and their due dates. For the course's complete CHECKLIST, the link is "COMPLETE INTERACTION OF COLOR COURSE INDEX & CHECKLIST".
ACRYLIC PAINT & COLOR MIXING STUDIES
5. HUE, VALUE, AND INTENSITY SCALES
5.1. We shall use paint to practice painting and to train your eye in the use of transferring what your eye sees from paper to paint.
5.2. Use acrylic paint on white paper. Make all colors opaque by adding white to them. Note that acrylic paint dries darker than when wet.
5.3. Nine is the ideal number of steps although 3, 5, and 13 also work.
5.4. The steps or jumps between all colors must be even and equal.
5.5. The test for even and equal steps are if the edges are equally hard. If the middle color goes toward or blends more easily into one color on either side of it while the color on the other side of it is harder with a greater jump, then some of that color must be added to balance the middle color. You can determine this by squinting hard to eliminate color as cones in the eye shut down and black and white rods take over dominance.

|
Hue 4- middle color between Hues 3 & 5
|
Hue 5- middle color between Hues 4 & 6 |
Hue 6- middle color between Hues 5 & 7 |
Hue 7 - middle color between Hues 5 & 9 |
Hue 8- middle color between Hues 7 & 8
|
Hue 9 |
Value Scale hue toward hue mixed with white
5.6. Before beginning the studies, add some of Hue 1 to the last Hue (3, 5, or 9) and some of the last color to Hue 1. This diminishes the intensity jumps between pure Hues 1 and the last one (3, 5 or 9) and the colors next to them.
5.7. Make a note to notice what happens to the colors as they are mixed.
5.8. The solutions for the study will demonstrate:
5.8.1. One hue study that goes from one hue to another.
5.8.2. One value study that goes from dark to light, light to dark, light to light, or dark to light.
5.8.3. One intensity study that does from bright to dull, dull to bright, dull or dull or bright to bright.
5.9. Additional studies not required are to:
5.9.1. Go from a hue to a hue using colors of equal value. This works better with tints.
5.9.2. Go from one hue to gray.
5.10. CHECKLIST - 3 STUDIES
6. MATCH A COLOR AID
6.1. Take any color aid and match it for hue, value, and intensity with acrylic paint. Dry acrylic on a corner of the color aid paper to see if your match is precise.
6.2. The solution for the study will demonstrate
6.2.1. One study as close as you can get to a perfect match.

7. PAINT A MIDDLE COLOR BETWEEN TWO COLOR AID HUES
7.1. Select two different hues. Paint the precise middle color between them.
7.2. Note: YELLOW is a killer color because of its light value. It is the most difficult hue to use in this study and sometimes in many other studies.
7.3. The solution for the study will demonstrate:
7.3.1. One study as close as you can get to a perfect middle color. In other words, the edges between the middle color and their parent hues should be equal.
7.4. CHECKLIST - ONE STUDY
