Since it's a bedroom, you should go for a soothing, sleep inducing color like a light green. What way does your room face? Stay away from yellow greens if it faces south and opt for silvery green sage instead. If it gets northern light, then go for the pale pink or soft salmon. Stay awaay from bubblegum pink, which will eventually drive you crazy. = }
Since neon colors can be fun, but also electrifying, think about buying some blank stretched canvas from your local craft store. Vary the sizes if you want. Get some small paint cans in the neon colors that will look great with your wall color (carry the sample chip with you) and paint each canvas (including the edges)with one color. If you feel they're too "flat", try splattering some of one of the other colors onto one of the (dry) canvases. You may even decide you want more color on just one canvas, like a self-made Jackson Pollack! Another idea is to paint a small canvas the same color as the wall, then paint stripes or spray flecks of a bold color on it and hang it in a small area, like a short wall by a closet. The contrast paint seems to hang in front of the wall.
You can get sheers on sale at LNT.com and use one of the many coupons that appear regularly in the newspaper, or try Domestications. They offer super wide sheers really inexpensively that look luxe on the window.
Go to a fabric or craft store like Hobby Lobby and look at their nylon netting (not the bridal illusion which is way more expensive). For less than a $1.00 a yard, you can buy yards of bright net. Get a step ladder, some rubber bands, and maybe some coordinating or contrasting ribbon if you want. Lay out the netting on the floor and fold it over on itself. Gather the cut ends together and rubber band them to one end of your decorative rod (not the one with the sheers). Wrap the netting around the rod as many times as you want, rubber banding the end to the rod. Now distribute the twists evenly and begin "opening" them into pouffs. Since the netting is wide and you have a double layer, it gives an airy, fun look. You can tie ribbons between each pouff if you want.
Do you have carpeting or hardwood on your floor? Try to match one of the colors in the leopard print to your floor. Look for a fun throw if you don't want to do the duvet and pillows in the print. Pick another of the colors in the leopard print for the dust ruffle, probably black in a tailored look which will make the bed pop.
If you have carpeting and it's staying, find something that is the same color and take it with you when you go paint shopping. You could even cut off a little fiber sample from the back of your closet and tape it to a white index card. It's important to work with the carpet, since it's the grounding in the room. Hope this gives you ideas.
