I'd rather have someone lie to me about what they think about the color of my shirt out of concern for my feelings (that's called 'love') than be brutally honest and share their hurtful opinion about it. I'm totally convinced God approves the former well over and above the latter. The well being of others (love) is the highest and greatest concern.
Not sure why somebody would comment on the colour of your shirt unless you asked them. If you ask them then you invite them to be honest, they then know that you trust them enough to be honest. If they know that then could be honest and say "That colour doesn't suit you" and I'm sure your feelings would not be hurt, or they could say "if you love it you wear it" I ask my wife all the time because my sense of dress code is terrible. I even take picture if I'm clothes shopping and send it to her and ask her what she thinks.
If someone comments on the colour of your shirt whose opinion you have never sought before then to me they have no cause to comment in the first place and I would think to myself why on earth are they commenting.
I know we are only talking about a shirt here and it's a point you are trying to make. Truth is colour of clothes, what music we like and other things we shouldn't be afraid to answer honestly when asked and vice versa.
An example may be if I'm driving a distance in the car with a friend I would want to put music on. I may say "I like Elvis do you? They may say no I don't so I wouldn't put it in on, yet they may say put it on I don't mind"
I would hope I would be one who says " not my cup of tea but put it on"
If don't want a truthful answer then don't ask the question.
I'm not sure God approves a lie to save someone's feelings. I may be stretching it bit far but if a person feels the need to lie to us then they may not be comfortable with us, and there must be a reason, if they are not comfortable with us then they may try to avoid us. Possible kind loving relationships will not mature where we can then have a relationship and be honest with each other on issues that really matter.
Building each other up in Christ.
