Playing With Paint (and Asking Sherwin Williams for help)

We are working on the addition to our house again.  The inside is progressing quickly but soon we need to deal with the exterior, which has had plywood but no siding for a year now.  It will be difficult to match the existing siding, so I am trying to design a total plan for the house that makes the areas with different siding look intentional and not haphazard.  I am thinking about playing with paint to both unify some areas and create accents in others. I have been googling and pinning lots of ideas related to log homes (what we currently have) and craftsman style cottages (the direction that I want to take out house). In the process, I stumbled onto Sherwin William's website.  Do you know about their color selector website?  You can upload a photo of an interior or an exterior and then select different areas to "paint".  It takes a little time to get the hang of masking off different surfaces to receive different colors all in the same image, but it is SO cool to see the options on my house with my green roof effecting every color choice! Here is where I started tonight.

And here are four different color schemes that I found sing the color selector website.  We are looking to add cedar shakes on the peaks of the roof and probably a vertical board and baton siding on the addition (currently covered in Lowes brand Tyvek).  The new siding will be painted to match the stain on the wood log siding on the front of the house, so I wanted colors that log siding comes in or weathers to become.  I think we would just stain the wood, but I am tempted to paint the white caulking on the log siding part so that the white stripes aren't distracting from making a cohesive image. Is that wrong of me to want to make my log cabin look less log like?  Id love to hear your thoughts on mismatched siding, painted log cabins, and my color ideas.  I have two favorites.  What are yours?
