Nothing since I don't know how.
Whether using a lab or printing your own at home, getting correct color and density in a print requires:
Monitor calibration (linearizing the monitor output so it makes gray at all brightness levels between red 0, blue 0, and green 0, and red 255 blue 255, and green 255 (on an 8-bit scale).
Monitor profiling (creating a lookup table for your CALIBRATED monitor that matches its color output to an international standard.
Both the above are accomplished with a kit from Datacolor or Calibrite. The kit includes a "puck" (colorimeter or spectrophotometer) that connects to your computer, and software that guides the calibration routine and performs the profiling.
The result is a known-accurate monitor that allows you to adjust your images in software and know that your lab or printer will produce an image that looks very close to what you see on the monitor.
My recommendation is that unless you are willing to buy and use a calibration kit on a monthly basis, that you not adjust images and that you not print your own work at home.
Printing great color requires using either the manufacturer's own photo papers and inks, or using third party photo papers with ICC profiles that you download and install in your operating system. Printer manufacturers supply generic ICC profiles with their printers for each of their own papers, and usually install them along with the printer driver software. Red River, Hahnemühle, Moab, Magic, and other third party paper vendors have downloadable profiles on their web sites for most popular PHOTO printers. They also supply instructions for installing and using those. Remember, you need a different profile for every combination of printer model, ink set, and paper surface you intend to use!
Better labs (commercial color labs) will supply you with profiles for their printers, so you can make final adjustments to images while doing "soft proofing". Soft proofing applies the lab or printer/paper/ink combination profile along with your monitor profile so you see the closest simulation of color in your files.
If I were going to print very often at home, I'd probably get an Epson EcoTank Photo ET-8550 ($800), which uses six dye inks sold in pretty good-sized bottles. The Canon Pixma Pro 200 ($600) is another good choice, but it uses dinky little cartridges that tend to be very expensive.
