Abstract
We report on an ongoing study of the optical-near-IR colors of globular clusters (GCs) in E galaxies. The motivation is that (i) HST images give the necessary resolution to discriminate against foreground stars and background galaxies, while the photometry goes very deep; (ii) Near-IR observations reach only the brightest clusters, but provide a much larger color baseline which is very useful to e.g., identify intermediate-age clusters such as those found in the LMC and in NGC 5128 (cf. Minniti et al. dy1996, tiApJ, vn467, pp221), and to measure more accurate metallicities, particularly at the metal-rich extreme of the metallicity distribution.
