Low luminosity radio-loud active galactic nuclei (AGN) are generally found inmassive red elliptical galaxies, where they are thought to be powered throughgas accretion from their surrounding hot halos in a radiatively inefficientmanner. These AGN are often referred to as "low-excitation" radio galaxies(LERGs). When radio-loud AGN are found in galaxies with a young stellarpopulation and active star formation, they are usually high-powerradiatively-efficient radio AGN ("high-excitation", HERG). Using a sample oflow-redshift radio galaxies identified within the Sloan Digital Sky Survey(SDSS), we determine the fraction of galaxies that host a radio-loud AGN,$f_{RL}$, as a function of host galaxy stellar mass, $M_*$, star formationrate, color (defined by the 4000 $\angstrom$ break strength), radio luminosityand excitation state (HERG/LERG).  We find the following: 1. LERGs are predominantly found in red galaxies. 2.The radio-loud AGN fraction of LERGs hosted by galaxies of any color follows a$f^{LE}_{RL} \propto M^{2.5}_*$ power law. 3. The fraction of red galaxieshosting a LERG decreases strongly for increasing radio luminosity. For massiveblue galaxies this is not the case. 4. The fraction of green galaxies hosting aLERG is lower than that of either red or blue galaxies, at all radioluminosities. 5. The radio-loud AGN fraction of HERGs hosted by galaxies of anycolor follows a $f^{HE}_{RL} \propto M^{1.5}_*$ power law. 6. HERGs have astrong preference to be hosted by green or blue galaxies. 7. The fraction ofgalaxies hosting a HERG shows only a weak dependence on radio luminosity cut.8. For both HERGs and LERGs, the hosting probability of blue galaxies shows astrong dependence on star formation rate. This is not observed in galaxies of adifferent color.[abridged]
