Blue has been used for a while on Platinum PP watches ( as, for example the 5110, 5130, 5070 ... ).
Now, the question is: Will you get rid of it, compared to a 5140G?
That is the true question.
In your case, from what I read, you'd better pass on it: You're not convinced, you have doubts, and you seem to really appreciate the understated 5140 G.
I would keep this last one.
Best,
Nicolas.
