answer:Paint is a great tool, I found it necessary to paint one room orange sunshine, on accent walls I picked a lighter hue to bring out the cream. As seen as it drops over the ocean near sunset. It wakes me up, lightens my mood. Light turn off the flourescence and play with lamps if you don’t want to do reno. Plants, I have an affinty for indoor herbs, but whatever you choose they freshen the air make it smell better and soften a room. There are water fountains. Very soothing sound. But they can get messy or be annoying so optional you could always go for music. Personalize the room a little, bring a part of you that harmonizes with the rest of the room. People can tell when a space is personal or cared for in a way that reflects the ambiance you wish to create. Keep it simple but spread across the whole room a rug, wall art.
