The pictures are from yesterday when I played around with Alice, but I need to do a bit cleaning in my room before I can give Alice her faceup, so this is it for now.
The less natural light there is, the more clear yellow or blue the motif becomes. On the first picture with the blue diffuser, the sandy color of the dress' shirt shines better through the blue - if that makes sense. It's really a great tool to play with. I like how it's not like a filter you just put on top of the picture, but it's more integrated I think. ^^
The white diffuser gives the picture a more warm feeling in my opinion. Here in Denmark, we have a very cold and clear light so it is normally only in the summer we get a chance at warm light. I think I will be using this diffuser most ;P
