You really can get candle wax out of carpet. It's not always easy, but wax can be removed with patience. Dyes from the wax are a different matter. Getting those out depends on what's in the particular dye.
Start by scraping as much wax out of the carpet as you can, with a spoon. Afterwards, put an ice cube or two on the wax to freeze it, leaving them there for a minute. This should harden the wax enough to break it up and get more of it out.
To get the rest of the candle wax out of the carpet, cover the spot with a clean brown paper bag, and place a clothes iron on it, set on low. This liquifies the wax and lets it transfer to the paper. Use a new paper bag as often as necessary until you get all of the wax. This can take some time.
