PSA- Importance of Color Swatching

The above demonstrates why you should swatch your paints and markers!  The first two swatches are Van Dyke Brown, and the color varies hugely between Cotman and Grumbacher, two student grade brands.  The Cotman pigments are much lighter than the Grumbacher for a color that should be a rich, dark reddish brown.  The bottom three swatches are for Sepia- Blick's, Cotman's, and Winsor Newton.  The Blick's is rich and dark, but opaque, the Cotman's Sepia is more of a Van Dyke Brown, and the Winsor Newton (a professional grade paint) is the right hue and would withstand repeated washes.
