Steeping is a process that happens to e-liquid over time. It's also used in the production of e-liquid. Steeping is letting the juice “age” over a period of time to improve or strengthen the flavours making the e-liquid darker in colour. It's also dependent on the nicotine strength, the higher the nicotine the the darker it will appear.
