I disagree: the words you read are interpretations from the writer. The writer is explaining the beauty THEY see through their OWN vocab. When you look at a picture your brain tells you what is beautiful to you and you interpret the beauty in a picture in your own way.
Do you mean lackluster?
if that is the word then the root word would be luster and the affecting word be lack because you would be lacking luster. does this help?:)
The answer is c hope it helped
