In this second study using Arthur Stern's book, "How to See Color and Paint It", I went to project 4 'How Plain is a Plane'. This is the set up.
In the set up box are the following construction papers: Red, Yellow, and Blue. The lamp is facing more of the top of the box than below.
The colors I used to paint with are: Winton White, Winton Cad Yellow Pale, Cad Red Light, Winton Permanent Alizarin Crimson, and Winton Ultramarine Blue. Because I'm using a palette knife, using a lot of paint, and these are studies I'm using for my own set of studies (and I had some in my drawer) I chose to use mostly Winton paints. Here is my thought on using student grade paint. As far as I can tell, and from the small amount of research I've done, student grade paint does use, for the most part but not always, the same paint that is used in professional grade paint. But a lot less of the pure material is used and much more fillers are added, such as oil. Therefore, tinting strength is much, much lower. This goes for Winton Titanium White as well. I pretty much stay with professional grades of paint, and I might add a bit of Winton if, for example Ultramarine Blue, is a bit dry instead of oil to get it to the right consistency. I am essentially adding a colored oil to a professional grade paint. Second, student grade paint is definitely not as luminous. Third, student grade does not always use pure materials. If you see the word 'hue' added after the color name, it is NOT a pure color but a combination of colors to get close to the color that is on the label. This will act differently than a purer color when you go to mix it. So my thought is that whatever you decide to use, know it's pros and cons. In these studies I'm using a combination of both student grade and professional grade paints.
Now that that is explained, look at the photo above and you will see like all things, one color is affecting another. Notice how much red is reflecting on to the blue and how much blue is reflecting on to the yellow. Also see some of the yellow reflecting back on the red? Let's analyze what's going on and what colors to choose to paint with.
