Assignment: Hue, Value, Chroma Charts. Color Gouache Exercises.

Schedule

Due Monday, March 19th- 
1" swatches for the following:
- Color wheel (you will need a swatch to match each color on the color wheel I gave you)
-Achromatic grays that correspond to each color on the color wheel. (greyscale)
- Colors for psychological, historical, and subtractive primaries
-achromatic greys for new value scale (11 steps)
-Please cut out all your swatches into 1" strips. We will put these together in class. 

 
Here is the schedule for the rest of these exercises. 


Due Wednesday, March 21st- 
1" swatches rough-cut for the following:

• 10-step chromatic scale in yellow (only chroma shifts, no shift in value or hue)
• 10- step chromatic scale in violet (only chroma shifts, no shift in value or hue)

Note: cut your swatches to 1" height, but leave the other sides longer. 

Due Monday, March 26th-
All of the following must be completed for start of class. Please bring rubber cement, xacto, blades, and ruler to class. You will be mounting in class. Must have the following 1" swatches COMPLETELY CUT AND READY TO MOUNT at the beginning of class:

Chromatic Scale swatches (all cut into 1" squares- we will mount in class)

• 10-step chromatic scale in Primary Yellow (from tube)
• 10-step chromatic scale in Violet (to match your color wheel)
• 10-step chromatic scale in Primary Blue (from the tube)
• 10-step chromatic scale in Green (to match your color wheel)
• 10-step chromatic scale in Primary Red (from the tube)
• 11-step Achromatic Gray Scale (if you had an A on the first one, you can use it)
• 12 colors for color wheel

12 Achromatic grays that correspond to color wheel (1inch squares)

Primary Color Charts (mounted flush to edge of paper (8.5 in x 8.5 in)

• 4 colors for psychological primaries (Red, Green, Yellow, Blue)
• 3 colors for historical primaries (Red, Yellow, Blue)
• 3 colors for subtractive primaries (Magenta, Yellow, Cyan)

Due Wednesday, March 28th- 

FINAL CRITIQUE- Everything Mounted and ready for presentation.

Color Mixing Tip: 

Mixing with grey will commonly cause your Hue to shift (an unwanted color change) These shifts are accentuated if the grey is somewhat bluish, as results from mixing most black paints with white. Understand- the black paint you have is not pure black. It is a very, very dark violet or blue. 

You can fix this unwanted shift of hue by adding a tiny amount of paint to your mix so that it brings it back the other direction on the color wheel. 

Example: If your yellow starts shifts toward green, add a tiny amount of strong orange or scarlet to it to send it back the other direction on the color wheel.

Required Research: Intro to Color Theory. Due Monday, March 19th.

After our in-class lecture today, I am assigning you the following three readings to do before class on Monday,  March 19th. They are all available on this website. 

I recommend reading this BEFORE attempting to do your painting assignments. 

Reading 1- Intro to Color Theory

Please start by reading the prologue. It's a great resource for understanding color theory and it's development. Don't worry if you don't understand it all- there is a lot of information here. Also, you can listen to the writer reading it in the video below

Reading 2- The Dimensions of Color

Read the section titled, The Dimensions of Color. We will use the terminology presented in the reading to discuss the three attributes of color. These attributes are applied to both additive and subtractive color. The author uses the terms Colors of Objects (ex. paint or ink), and Colors of Lights (ex. a computer screen). The three Dimensions of color are: 

1. Hue
2. Chroma/Saturation
3. Value/Brightness

Reading 3- Paint Mixing Principles

The last reading for Monday will be the part on mixing paint. Please read the sections on white, grey, black and hues. Again, don't worry about not understanding everything. Just be sure to understand the basic ideas. 

For Class on Monday, March 19th

Please bring your bristol board pads to class along with your gauche and painting supplies. We will be painting in class.

Primary Colors. Swatches due Monday, March 12th.

Hi Class,
Here is the information on the three sets of Primary Colors. You will need to research David Briggs website to be sure you understand the concepts and differences between the three types of Primaries. 


Due Monday, March 12- Good painted gouache swatches for each of the Primary Color sets. 


Here is a breakdown of the perfect swatches you will need to paint and how many:

• Yellow- 3 swatches total.
• Red- 2 swatches total.
• Blue - 2 swatches total.
• Cyan (Green-Blue)- 1 swatch total.
• Magenta (Blue-Red)- 1 swatch total.
• Green - 1 swatch total. 

For Monday- Please bring in all your painting supplies and cutting supplies. 

From David Briggs website:

"Ideal yellow, magenta and cyan colorants would be the optimal primaries for paint mixing, if such pigments existed. However, even today our best magenta and cyan pigments are well towards red and blue respectively, compared to the ideal magenta and cyan subtractive primaries. No high-chroma pigments are very close to an ideal magenta hue.

The closest high-chroma oil painting pigment is quinacridone magenta (PV 19), which is distinctly redder than ideal magenta. 

The closest popular oil painting pigment to an ideal cyan is the green shade variant of phthalocyanine blue (PB 15.3), which similarly is distinctly bluer than an ideal cyan. 

Note: Cobalt green is closer to ideal cyan in hue, and does mix some blue-green colors not obtained using phthalocyanine blue alone as the primary, but yields fewer colors in the bluish range. It is also more expensive, and being opaque is less suited to mixing dark colors. 

Yellow pigments are available in an essentially continuous range of hues, and a pale or lemon yellow seems to provide the optimal gamut of colors."
