You know it's great that you have such a fabulous place to move into and something to look forward to in a way so that this break up isn't a complete downer. It will be such a nice way to really make a new start at things.
And I agree with Casey...definitely add some contrasty accents of color into the room. Even a strategically placed vase with vibrant colored flowers could really be nice. It would just go overboard I think to make everything really bright and colorful. A few well chosen accents would make the room perfect. I think red is a great choice, but just as a thought, purple is the compliment to yellow which then means that that would be the color that would stand out most, so even if you don't use purple exactly, things that have that hue a little would go well (like a red that leans towards the purple side as opposed to the orange side).
I definitely can't wait to see these pics when your place is done. How exciting!!
