Client: I don’t like that blue, make it a bit lighter. Just a small bit!
I send the (unchanged) file back to her.
Client: Hmm, ok thats too light, make it a bit darker.
I send the same file - again, unchanged.
Client: Ok just ad a hint of brightness and we’re done!
Again, same file, unchanged.
Client: Perfect! Has anyone told you that you are amazing at what you do?
