Jan 25, 2018

Have you been experimenting with your paint colors lately? Do you have questions about different colors and the best way to mix them? You are in luck! As I’ve been promising, our special color episode with Gamblin featuring Scott Gellatly and Robert Gamblin is here! In our conversation, we go over the pigments used in modern paints, the emotional content of a color, what makes student grade paints, “student grade,” the best paints to use for plein air painting, and so much more. You don’t want to miss a minute of this in-depth and fascinating conversation with Robert and Scott!

Why modern paints have more pigments.

Have you ever wondered why modern oil paints have so many more pigments than older ones you see on display in galleries and museums? What has changed with the process over the years to account for this? My guest, Robert Gamblin was kind enough to give a bit of a history lesson on the production and use of colors and pigments from historical eras and why it’s so different today. I’m excited for you to get the chance to learn from Robert’s expert perspective and dig a little bit into the process and production of the paints you use day in and day out.

What is the emotional content of colors?

Did you know that colors have an emotional content? How does that impact the paint production process? Robert Gamblin says that the emotional content of a color is its primary communication. He goes on to give the example of Cadmium Red Medium, saying that it presents as a very hot and intense color, it could be used to express the feeling of rage or the intensity of a love that you can’t handle. Robert contrasts this color with Magnesium Blue Hue, which presents as a very cool color. I hope you find Robert’s explanation of the emotional content of colors as fascinating as I did!

What makes student grade paints, “Student grade?”

You’ve probably used student grade paints before, but have you ever wanted to know what makes them, “Student grade?” Do you still use student grade paints for some of your projects? My guest, Robert Gamblin took the time to explain what student grade means and how it varies from some of the other paints they offer. According to Robert, the difference between student grade and more premium paints comes down to the pigments. At Gamblin, student grade paints are made with 50% of the pigment load that is used in their artist grade paints. The remainder of the student grade paints are made up of extender pigments, other than that, the production quality and process is the same as the rest of their top quality products. What ways will you use student grade paints in the future?

The different characteristics of black oil colors.

The last time I had the chance to speak with Robert, we talked about the different characteristics of white oil colors. This time around, Robert goes over the characteristics and uses of black oil colors. He starts off talking about the most commonly used black, Ivory Black which is made of burnt bone. Ivory Black is so common because it is an all-around good mixing black color. Robert then goes on to explain how Mars Black differs from Ivory Black because of its opaque nature. Mars Black is best used when you want to utilize black as a color in your paintings because of its strength. Robert has so much to say about all the different blacks and how to best use them, I hope you enjoy his expert perspective!
