Guest bathroom

I love the rich colors of the fall and winter seasons...with that said I'm so over winter!  It has been overcast for days.  The plus side is I have time to work on projects around the house.  Now, normally my guest bathroom is light filled and inviting but today it seems too dark.  So I snapped a few quick pictures to get some ideas on how I want to decorate it for spring.  Do you change all your rooms in the house to match the seasons?
