Smaller areas of color, and colors that are closer in value tend to create more convincing blends.
Blurring: Two colors of similar hue, value and saturation will seem to blur into one another, making it difficult to determine their edges. This works best with ANALOGOUS colors—Colors next to one another on the color wheel
