REFERENCE: Four levels of saturation

The chart and definitions below introduce the four basic levels of saturation
















PRISMATIC COLORS 
are as pure in hue as is possible with pigments. Once a pure color has been altered through color mixing, it ceases to be prismatic (except when the admixture is a closely related hue, as when mixing yellow-orange into yellow).

MUTED COLORS 
range from rich colors that lie just outside the prismatic zone, to the most saturated chromatic grays. One can create muted colors by adding black, white, or gray to a prismatic color. Adding the complement of a hue will also diminish its saturation and produce
muted color.

CHROMATIC GRAYS 
exhibit a subtle, yet discernible hue. Except for the proportions involved, they are mixed in exactly the same manner as muted colors. Chromatic grays simply require larger quantities of black, white, gray, or the complement.

ACHROMATIC GRAYS 
compose the inner circle of the color wheel. Grays mixed from black and white are achromatic because, like black and white, they lack perceptible hue and saturation. Achromatic grays can also be produced by precisely intermixing two complementary colors so that each hue cancels the other our. Insofar as a gray registers the slightest amount of perceptible hue it should be considered a chromatic gray.

SAMPLES COLOR CHARTS BELOW SHOWING PROCESS OF LEVELS  OF TRANSFORMATION FROM A PURE SATURATED HUE DOWN TO CHROMATIC GRAYS.

THIS EXERCISE MUST BE PUT INTO PRACTICE IN SKETCHBOOK IN ORDER TO UNDERSTAND THE PROCESS AND THE GRADUAL SHIFTS FROM MUTED TO CHROMATIC GRAY.

This is to be analyzed and strategically applied to the composition exercises you are creating in class. 

You must apply the appropriate use of chroma considering range of values, different levels of muted hues  your composition. Use the muted composition as a guide to following the same hues and same values but using a chromatic gray palette. 

Result: 
TWO of the same compositions, same chroma,  same values. 
one using muted palette.
one using chromatic gray palette. 

Pay attention to the grayscale value scale as a guide to applying the different value shifts in each hue. IMPORTANT to compare grayscale value in relation to value in hue.
