We argue that if color-superconducting quark matter exists in the core of aneutron star, it may contain a high density of flux tubes, carrying flux thatis mostly color-magnetic, with a small admixture of ordinary magnetic flux. Wefocus on the two-flavor color-superconducting ("2SC") phase, and assume thatthe flux tubes are energetically stable, although this has not yet beendemonstrated. The density of flux tubes depends on the nature of the transitionto the color-superconducting phase, and could be within an order of magnitudeof the density of magnetic flux tubes that would be found if the core weresuperconducting nuclear matter. We calculate the cross-section forAharonov-Bohm scattering of gapless fermions off the flux tubes, and theassociated collision time and frictional force on a moving flux tube. Wediscuss the other forces on the flux tube, and find that if we take in toaccount only the forces that arise within the 2SC core region then thetimescale for expulsion of the color flux tubes from the 2SC core is of order10^10 years.
