Know Your Medium

Know Your Medium

I want to stress the importance of knowing your medium.

While working on a portrait I needed to fix some errors.  The paper was off white, so I would have to make my own correction fluid to color match the paper.

The plan is to mix a brown with white until the color is as close as possible.  I have two colors of brown, Burnt Umber and Sepia.  One is warm and the other is cool.

When mixing them with the white I discovered that the Sepia turned grey!  Not what I was expecting.  I quickly abandon the idea of using the Sepia.  Now I know that if I need a toned grey I can use it.

The Burnt Umber mixed well and gave me the correct tone I needed for the paper.

Below is the swatch tests I did.

You can see the differences in color.

Not all browns are the same.

The bottles are backwards!  The Sepia (bottle on the right) starts in the middle.  The Burnt Umber (bottle on the left) starts at the top.  I did several more swatches before I started on correcting the drawing.
