How the painter’s palette is organized can make a difference in efficiency for the decorative painter.
Use a consistent arrangement to organize the colors on your palette: Place the white in the upper left-hand corner, then align warm colors in a row to its right, and cool colors in a column below it. Keep a palette cup filled with glaze by the thumb hole.
Of course, if you’re a lefty, you’d flip this organization to suit you.
Here are some palette’s of interest.
