If your house is well insulated, the darker siding shouldn't affect internal temperature, as nsc6 said. The only way you can assure you won't tire of the house is to use something like HardiPlank that you can paint in 7 to 10 years if you tire of the color. It's quite a bit more expensive than vinyl though. Will you be living here full time or is this a vacation home? If it's a vacation home that you won't be driving up to every day, I think it would be a nice change to have something a bit different than you see driving down your street to your home every day. If it's a weekend and vacation getaway, it should feel special. Honestly, it should feel special even if it's going to be your everyday home. You could leave the brown window trim. It would work well with the cedar siding.

You have a very cute house!! I think something in keeping with the original look of the siding would be best if feasible. What color is the roof? I am wanting to accent it with green on the door or the porch but it really is classic and adorable as is (with a good cleaning). I think it's hard to match that sort of hunter green with some sort of other color. Can you paint or replace the accent on the awnings? And I think trim in a different color than the siding is going to make it look smaller and choppy with the awning lines and trim. No shutters please - too much going on with the awnings to add shutters too. Maybe someone else will have a fabulous idea for you!!

I'll be posting pics on a new thread soon of our 1950 Florida ranch house to ask for help with exterior colors. This thread already got me started with ideas and I hope you all will be just as generous with your great advice as you were with A P. Houzzers are the best.

The house is adorable. I actually like the yellow, bright as it is. No shutters, and yes, replace the storm door. You live in northern Michigan, you definitely need a storm door. I do prefer one with a lot of glass, but, a requirement for me, is that it also has the pull down storm to reveal a screen. Its pretty nice to be able to open the top a bit, and let fresh air into the house. Something like the one in this link. https://www.lowes.com/pd/LARSON-Tradewinds-Bevel-White-Full-view-Aluminum-Storm-Door-Common-36-in-x-81-in-Actual-35-75-in-x-79-75-in/50375006
