When describing something as "abnormally white," there are a variety of synonyms that can be used to convey a similar meaning. For instance, rather than describing something as abnormally white, one could use words like "unnaturally pale," "chalky," "bleached," "ghostly," or "pallid." These terms suggest a lack of color or a peculiar brightness that deviates from what one might typically expect. Alternately, one could use more descriptive phrases such as "paper white," "snow white," or "bone white" to convey a sense of whiteness that is particularly stark or distinct. Whatever words are used to describe this characteristic, they should be chosen carefully to ensure they accurately express the desired meaning.
