It’s good to outline the fact that different colors, designs and pictures evoke different feelings and emotions. Thus where you would like to hang the images of Irish culture does matter a lot. For example, you can use "Lawn in front of a landscape, Roscommon Castle, Roscommon County, Republic Of Ireland" by Panoramic Images in a room with a brown background. It can work with both a lighter or darker shade of brown. Irish culture art is rich and endows you with several options that will definitely fit your bill. You can experiment with different sheds and apply a number of accessories to be able to achieve that solid and elegant look.
