When we think of something being portrayed in a positive light, we might refer to it as "rosy pictures." While this phrase is useful, there are many other synonyms you could use to describe similar situations. For instance, you could refer to something being presented in an overly optimistic way as "sugarcoated." "Airbrushed" could also work, as it implies that a certain image has been polished or altered. Alternatively, you might use "idealized" or "romanticized" to describe a portrayal that doesn't accurately reflect reality. Ultimately, the exact synonym you choose will depend on the specific context and your desired tone.
