Cold does not directly cause colds, however it can have an indirect effect. Here is an excerpt from Everydayhealth that explains it a bit more
"Cold weather may be indirectly responsible for colds, however. Vasoconstriction — when blood vessels close to the outside of the body, such as those found in the nose, narrow — leads to dryness. "This dryness compromises the nose's ability to filter infections," Belilovsky explains. "On returning to warm air, rebound vasodilation occurs, where your hands get pink and your nose starts running as blood returns to it." The cycle continues if the runny nose is severe enough to cause mouth breathing. Bypassing the nose's ability to filter inhaled air, combined with dry indoor air, allows the inhalation of virus-bearing mucus, which may trigger colds and lower respiratory infections."

I hope that makes sense for you.
