The Artist's Triadic Color Wheel:

Brief discussion of the terms on the color wheel as an introduction to the workshop.  We will return to the color wheel later. This workshop will use this triadic artist's color wheel methodology of primaries (as well as the Munsell Circle's)  See: David Briggs:  The Dimension of Color for a description of more fully developed, technically accurate systems. 

 Many color wheels:


From Newton to RGB 

Newton's Prism: 1665

Digression: What is Color?:  

Briggs' Spectrum


For an in-depth discussion of Color: see What is color? In summary: As proposed by Young and Helmholtz in the 19th century, the trichromatic theory held that three receptors sensitive to the parts of the spectrum seen as red, green and blue or violet generated fundamental sensations, and explained the sequence of spectral colours as successive combinations of these three sensations in changing proportions. Yellow was considered to be one such "compound" sensation composed of red and green sensations. In the modern zone theory, an updated form of the trichromatic receptor model is coupled with the opponent model of colour perception. The L, M, and S cones respond most strongly to the parts of the spectrum seen as yellow, green and blue-violet respectively, and the brain creates yellow/blue and red/green opponent colour signals based indirectly on signals representing differences in the cone responses. The sequence of colours of the spectrum is explained as the product of successive combinations of these red, yellow, green and blue opponent hue signals: (again from Briggs).

Classical, Impressionist and Modern Palettes from the Gamblin website

We might be discussing or experimenting with color wheels based on the following three sets of pigment palettes:

From the Gamblin Paint Website:

Classical, Impressionist, Modern Palettes

Paintings-clasical, impressionist, modern



And videos: Navigating Color Space by Gamblin (in the workshop, TIME PERMITTING, but I recommend that you look at these videos to reinforce the understanding of hue, value and chroma).

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 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

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

Image
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
