To create a chord progression in B major with a sadder tone, we can utilize the natural minor chords and the IV (4th) and V (5th) degree major chords, which have a more emotional and tense sound. Here's a suggestion for a chord progression:

Bmaj - G#m - E - F#

1. B major (I): B - D# - F#
1. G# minor (vi): G# - B - D#
1. E major (IV): E - G# - B
1. F# major (V): F# - A# - C#

Playing these chords in this order creates a progression that starts in the major key, but has a sadder and more emotional quality due to the inclusion of the minor and major chords from the 4th and 5th degrees.
