We present measurements of the color and luminosity dependence of galaxyclustering at z~1 in the DEEP2 Galaxy Redshift Survey. Using volume-limitedsubsamples in bins of both color and luminosity, we find that: 1) Theclustering dependence is much stronger with color than with luminosity and isas strong with color at z~1 as is found locally. We find no dependence of theclustering amplitude on color for galaxies on the red sequence, but asignificant dependence on color for galaxies within the blue cloud. 2) Forgalaxies in the range L/L*~0.7-2, a stronger large-scale luminosity dependenceis seen for all galaxies than for red and blue galaxies separately. Thesmall-scale clustering amplitude depends significantly on luminosity for bluegalaxies, with brighter samples having a stronger rise on scales r_p<0.5 Mpc/h.3) Redder galaxies exhibit stronger small-scale redshift-space distortions("fingers of god"), and both red and blue populations show large-scaledistortions in xi(r_p,pi) due to coherent infall. 4) While the clusteringlength, r_0, increases smoothly with galaxy color (in narrow bins), itspower-law exponent, gamma, exhibits a sharp jump from the blue cloud to the redsequence. The intermediate color `green' galaxy population likely includestransitional galaxies moving from the blue cloud to the red sequence; on largescales green galaxies are as clustered as red galaxies but show infallkinematics and a small-scale correlation slope akin to the blue galaxypopulation. 5) We compare our results to a semi-analytic galaxy formation modelapplied to the Millenium Run simulation. Differences between the data and themodel suggest that in the model star formation is shut down too efficiently insatellite galaxies.
