From Mark an arbitrary offer . Create a background image with your color and smooth the original image over it.

 convert -size 150x150 xc:"rgb(160,160,255)" source.png -layers flatten out.png

example

Edit If you don't want to worry about the image size, just change the background directly.

convert source.png -background "rgb(160,160,255)" -flatten out.png

Add - flatten to re-set the background color
