No. Not at all - you do want blue light in the day, that too helps keep your clock regular. (A constant morning time is crucial.) But all that won't compensate for blue light stretching into the evening.

Even way more red light at the same time as some blue light in the evening, while it helps reduce the effect of the blue, isn't fully effective.



Blue light indeed is bad for sleeping, painting your walls blue however does work.
