The antonyms for the phrase "made conspicuous" would be "hidden," "concealed," "obscured," or "camouflaged." When something is made conspicuous, it is made visible or noticeable, drawing attention to it. However, when something is hidden or concealed, it is deliberately kept out of sight, away from notice or attention. Sometimes it is necessary to obscure or camouflage certain things, such as military vehicles or weapons, to ensure they are not easy targets for enemies. Conversely, if something is already conspicuous, it may be desirable to hide or obscure it to prevent unwanted attention or scrutiny.
