Final answer:
The artwork Essex and Hester (6.2.22) uses a primary dark mottled red with various other colors layered on top, including primary colors and secondary colors like purple and orange, to create a vibrant, contrasting effect.
Step-by-step explanation:
Essex and Hester (6.2.22) feature swatches with a vibrant and complex color scheme, where the initial layer is a deep, dark mottled red. This color's intensity is enhanced by underlying layers that add depth and dimension. The artwork displays heavy black lines in each quadrant, incorporating primary colors. Above the midline, we can spot green, which being a complementary color to red, creates a dynamic contrast. The lower left quadrant features a blue color derived from a blend of cobalt blue and white, which contributes to the piece's three-dimensional feel. Secondary colors, purple and orange, are both mixed with white and lightly layered over the red, allowing the base hue to subtly show through.
