Colorless blending tools, often composed of wax, solvents, or oils, are used to smooth and seamlessly merge the strokes of colored pencils. They can be applied over layered pigment to create gradients, soften edges, and achieve a polished, painterly effect. For instance, a colorless wax pencil can be used to blend two distinct colors into a smooth transition.
These tools offer artists greater control over their colored pencil artwork, facilitating the creation of depth, dimension, and subtle variations in hue and saturation. They can transform rough, textured applications of pigment into luminous, velvety finishes. The development of such tools coincided with the increasing popularity of colored pencils as a fine art medium, offering artists expanded techniques and expressive possibilities.
