First off, this isn't really a yes or no question, this is an opinion.
My opinion is that photos that have been altered in any way should be marked. These days you never know what a person will do to say, get a job, advance a political agenda, or ruin the reputation of another person. The public has the right to the truth. Therefore, altered pictures should be marked or labeled in a way that differentiates them from others.
They used bright pastel colors is probably my best guess, but if that were the case I’m sure you would’ve picked that right?
