value study, grayscales:
mixing a black from primaries:
Color Mixing Guide from golden’s website
Mixing to achieve black and gray using Phthalo Blue G/S, Quinacridone Magenta and Hansa Yellow Medium
Step 1: Mix 1 part of Phthalo Blue (Green Shade) with 2 parts Quinacridone Magenta. The mixture will be correct when you perceive it to be the deepest blue without being described as purple. This is an approximate primary blue.
Step 2: Mix 2 parts primary blue with 1 part Hansa Yellow Medium.
Step 3: Once you master making your own black, create a grayscale like the following, by slowly introducing your black to titanium white.
download value study_grayscale.pdf for a guide.
-complete 2 grayscales:
one with self mixed black + titanium white
one with store bought black + titanium white
-employ a mid tone gray:
mix with water in various amounts, and record results
mix with matte medium in various amounts, and record the results
mix with matte medium + water in various quantities, and record the results.
-start with a photo provided in class.
study 1- geometric distillation
-distill the portrait down to simple geometric shapes using 5 values.
study 2- organic distillation
-using the same 5 values, further develop the information in the photograph into more realistic organic shapes
study 3- smooth gradient
-using the same 5 values, now make an attempt to blend these areas of value into smooth gradients, so no hard edge lines exist.
Odalisque in Grisaille, 1824–34 by Jean-Auguste-Dominique Ingres.
great article about grayscale underpainting / grisailles
and take a look at this video (although not exactly our pigments, but close).
