The factor that is not related to the blending of essential oils is the color of the oils. While the quality of ingredients, preparation method, and intended therapeutic effect are crucial aspects of creating effective essential oil blends, the color of the oils does not impact their therapeutic properties or their effectiveness in blending.

Quality of ingredients is fundamental, as the purity and potency of the essential oils directly affect the blend's overall quality. The preparation method also plays a critical role since the way oils are extracted and treated can influence their chemical composition and, consequently, their effects. Additionally, the intended therapeutic effect guides the selection of specific oils to achieve desired outcomes, ensuring that the blend serves its purpose effectively.

Color, however, is merely a visual characteristic that has no bearing on the oil's chemical properties or efficacy. While some practitioners might consider color for aesthetic reasons, it does not influence the therapeutic qualities or the blending process itself.
