Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

A solution that holds the maximum amount of a solute that will dissolve in a given solvent at a stated temperature and pressure, with any undissolved solute in equilibrium with the dissolved form. The IUPAC Compendium of Chemical Terminology defines a saturated solution as one whose concentration equals the solubility, the point at which adding more solute leaves the extra undissolved. The referent is a physical mixture at equilibrium, and the unit is a concentration, moles or grams per volume of solvent. Saturation here is a property of matter fixed by thermodynamics, not a perception, a market, or a reading from a body; a saturated salt solution and a saturated color share only the word.[1]
The perceived colorfulness of a hue relative to its own brightness, or in cylindrical color models the distance of a color from the neutral gray axis. Smith's Color gamut transform pairs defined the saturation coordinate of the HSV and HSL models, where a saturation of one is the purest form of a hue and zero is gray. The referent is a visual attribute of a color signal, and the unit is a fraction from zero to one, or a percentage. This is a statement about how vivid a color looks, not about how much solute a liquid holds; the same word names an equilibrium in chemistry and a coordinate in a color space.[2]
The condition in which nearly all potential buyers of a product have already bought it, so demand from new adopters approaches zero and unit growth stalls. In Bass's A new product growth for model consumer durables, the ceiling m is the ultimate number of adopters, and the market saturates as cumulative sales approach m. The referent is a population of buyers, and the unit is the share of that ceiling reached over time. Saturation here is a limit on demand set by market size, not a property of a liquid or a color; a saturated market and a saturated solution describe unrelated systems that happen to share a name.[3]
The percentage of hemoglobin binding sites in the blood that are occupied by oxygen, the quantity a pulse oximeter estimates as SpO2 and a blood gas measures as SaO2. Jubran's review Pulse oximetry describes oxygen saturation as the ratio of oxygenated hemoglobin to total hemoglobin, read from the differing light absorption of the two forms. The referent is the oxygen loading of blood in a living body, and the unit is a percentage, typically 95 to 100 in health. This saturation is a physiological reading that changes breath by breath, unlike the fixed equilibrium of a saturated solution or the standing ceiling of a saturated market.[4]
