Throwing A Party

So I'm on a budget and I'm starting to research lighting options for a small dance party ill be throwing. Im absolutely against cheap lasers and those obnoxious party lights that have a hundred beams and are 50 different colors. I want to have a clean setup not some high school rave party. Im coming to the conclusion that for my first purchase I would be good to get some wash lights and just illuminate the wall behind the DJ table with a nice violet purple color. Keep it clean and simple. Maybe if the party starts to heat up change that bitch to red. Honestly I just want to start a discussion here for cheap (But CLEAN) lighting options for a dance party. Ive always been so amazed and had so much respect for the production crews at some of these events I go to and I want to learn more!!! Any input would be great, maybe throw out some options or things you used when you were putting a party together on a budget. Any ideas or advice. Also, my buddy told me to check out the Chinese off brand stuff at its essentially the same, maybe not as high of light output or whatever but still essentially the same. Any thoughts or experiences going that route? Thanks for reading.
