I think The electron on the N side needs more than 10 electron volts because it also has to cross the potential barrier Vb, then it goes to the P-side and reaches the conduction band of P type. Now if it moves from the conduction band (higher energy level ) to the valence band (lower energy level ) they have to release as much energy as the energy gap. in case of red color it would be 1.8 ev or in case of blue color it may be 3ev.

u r the best
