Workshop Exercises




Preliminary Exercise (added):

This is an example of color mixing with paints, beginning with primaries, red, blue and yellow. 

We will use this exercise as a basis for additional color mixing. For the two pastelists in the group, try to find pastel sticks that correspond with the colors on this color wheel. If you try to mix all the colors from 3 primaries (red, blue and yellow) , you might try using cross-hatching or appropriate blending to produce the secondaries and tertiaries (as indicated)..Or select 12 pastels that most correspond with these wheel colors.

In the following example I use these acrylic colors:
Modern Primary Triad: Hansa yellow (HY), Quinacridone Red (QR) and Phthalo Blue (PB)  but choose whatever Y,R,B triad you want for this experiment/exercise.

Exercise.  The goal is to mix 12 colors from 3 primaries, red, blue and yellow. First mix the primaries to get secondaries, violet, green and orange.  Then mix these to get the indicated 'tertiarties'.  So the net result is that you will have counter-clockwise around the wheel, starting from the top:
yellow (Y)
yellow-orange (Y-O)
orange (O)
red-orange (R-O)
red (R)
red-violet (R-V)
violet (V)
blue-violet (B-V)
blue (B)
blue-green (B-G)
green (G)
yellow-green (Y-G)


So, practice mixing any colors you have to see if you can reproduce these twelve colors, preferably beginning with three primaries.  You might get some surprising and interesting results if you just begin with any version of yellow, red and blue.

Ignore the complements around the edge for this exercise (probably not helpful anyway; I put them there to juxtapose each color with its complement for my own benefit).

My color mixing is not perfect here.  I have copied  a version from the web for you to look at after this. (And you might leave a hole as was done in the web-image; it would be interesting to fill that area in with tints or shades or mixes t-o be discussed).




Note: the primaries have '1', the secondaries '2' and the tertiaries '3' above the name.

Second exercise:

Karen's Simplified Acrylics Color Wheel, perhaps considered a double primary color wheel: combinations of two primary triads:
Modern Primary Triad: Hansa yellow (HY), Quinacridone Red (QR) and Phthalo Blue (PB) (all transparent)
Impressionistic Primary triad: cad yellow medium (CY), cad red medium (CR), ultramarine blue (UB)

Note that these same colors are available in Oils and could be used. If I have time I will create the same wheel in oils. A first approximation could be done with one of the primary triads only as described in the email.


Paints used:
Utrecht Acrylics (but others okay):
Yellow:
    Hansa yellow (HY), biased toward green/blue
    Cad yellow medium (CY), biased toward orange/red
Red:
    Cad red medium (CR), biased toward yellow
    Quinacridone red (QR), biased toward blue
Blue:
    Ultramarine blue (UB), biased toward red
    Phthalo blue (PB) biased toward yellow
Titanium White (large)

Alternatives: Cerulean blue for phthalo, Cobalt blue for Ultramarine blue, but more expensive.
Aliz. crimson (fugitive color; I'm trying to stay away from this favorite) or Napthol red for the Quinacridone red.

The 'primary' sectors have two hues each as noted.  The mixes depend on the side of the color wheel.
Green = phthalo plus hansa yellow. Brighter green.  For landscapes the ultramarine plus either yellow would yield more muted greens.
Purple = ultramarine blue plus quinacridone red. More chroma since this blue and red do not have yellow in them. Again for landscapes, cad red medium would yield more muted purple/grays.
Oranges are the Cadmium yellow medium plus Cad Red Medium. But Hansa Yellow plus Q.R. would also yield a nice orange, a little more muted since has a touch of blue.



Tips for creating the wheel:
    Trace a large circle on a piece of canvas or use a protractor and place even marks around the circle, drawing lines through the center.  It might have been better to use a black magic marker to delineate the sectors (pie shaped).
    For acrylics keep the acrylics moist with spray so they do not dry out. Use a damp sponge underneath a disposable palette or a Masterson stay-wet system.
    Use clean water and brushes at all times. But to be safe start with yellow mixes since the yellow can be so easily contaminated. I laid out the colors that would be used for the yellows and oranges first and painted the yellow/orange part of the wheel first.  I wanted to make sure the paints remained moist. But with the sponge and the spray, the paints remained moist enough.
    Keep the palette organized.  It would be easier to keep the palette looking like the color wheel.  I did not take a photo but for this simple color wheel, it might make sense to place the colors on the palette in a circle format.

Exercise: create your own 'black' mixture and construct a gray-scale based on it. "Black" mixtures are noted in Karen's Double Primary wheel above (mix until look 'pure' dark gray/black add a touch of white ON THE SIDE to see if the resulting gray would be neutral). These blacks could be used to create tones (mixed with white) or shades. To make the blacks try a ratio of yellow: red: blue 1:2:4.

Exercise: Construction of the Munsell Color Wheel with your own palette. 

Exercise: simple image in the various harmonic schemes.
Exercise:. Use different color schemes for the same subject/scene.  

 Exercise: Analyze various paintings by master artists and/or artists who appeal to you.  Check color schemes. Could the paintings be improved?  Analyze your own paintings.

The Magic Palette

Exercise: Compare colors from the Color Wheel with the Magic Palette in the classroom. 



The magic palette provides mixtures of many popular colors with each other (acrylics and oils but watercolor pigments could be compared; see list below).  Note that the mixtures vary on the horizontal and vertical axes, with the vertical axis providing the dominant color-hue. In addition a small amount of white is added to each color (again varying from color to color and dominant axis to the other) to enhance the color.  See explicit instructions on how the palette is created in this link:

Color Wheel Revisited

We will be using the triadic color wheel from the Color Wheel Company to illustrate color relationships. a good resource is the book, Color is Everything, by Dan Bartges, a book with thorough descriptions of this tool (I will have it in the workshop for you to peruse).  Triadic Color Wheel from the Color Wheel Company: Study of the Triadic Color Wheel. The color wheel provides 12 hues around the circle on each side  On the one side we can see the effects of mixing red, yellow and blue and white and black with each of the 12 hues by rotating the wheel. This side also has a value scale that can be matched up with each of the hues to identify the value of each hue. The second side shows the tint, tone and shade for each of the hues. Directions are provided for determining analogous colors, complementaries , split complements, triads and tetrads. We will be discussing these at length. For a preliminary website link with definitions see:  http://www.tigercolor.com/col

(extra) Color Mixing on the web with online Apps with RGB and CMYK

May begin color mixing by studying color pickers provided by on-line tools. These are based on the RGB color wheel for web development, with its additive nature.   So first, an explanation of the RGB colors on the color wheel. We will see the representation of the R, G, B hues as 'hexadecimal'; e.g., red is #FF0000, where the FF masks the red perfectly and 00 masks the green and blue perfectly, but you will notice that the third hue in these tertiaries are masked with 7F. Binary numbers are 0's and 1's; 7 = 0111 in binary; F = 1111 in binary, so we see 0, 7 and F here. White would be FFFFF a perfect mix of R, G and B, while Black is 000000, a complete absence of an R, G or B. Yellow, magenta and cyan are complements of blue, green and red in this scheme.  In fact the hexadecimal notation for these complements has '1's in place of '0' and vice versa for the primaries and secondaries.  The tertiaries are aligned somewhat differently., with 7F m

(extra) Color Palette Examples

==================================== Limited palette of Don Finkeldei: www.finkeldeistudio.com. I have studied with Don and used his method extensively. He has many articles on the topic that are well worth reading and re-reading. His color charts, are quite useful and found in a new article on the website. His color palette consists of the Utrecht Artist Oils: cadmium yellow light, cadmium red light, ultramarine blue plus white, as well as alizarin crimson and viridian for transparent darks and sometimes the convenience color, cadmium orange.  He creates a few values of greys from a dark formed by the yellow, red and blue to be used in the mixing.  He also uses his AC/V transparent dark for accents. He pre-mixes his colors on the palette. ==================================== String Palette: I would like to include some material here on the palette of strings based on the Munsell theory, that formed my very first palette for oil painting. My instructor was the artist, Kei
