use "channels" and select the blue by clicking on the blue layer whilst holding down the control key, then create a new layer, fill the selection with white and pput the layer on either soft light or overlay and opacity on 50% or so.

play with the numbers, 50% could easily be 80 or 20%

in the example I selected the blue and filled it with #E1DB94 , and put the layer on soft light

hope this helps
