We present new BVRI photometry of Trans-Neptunian Objects (TNOs) and Centaurs obtained at VLT as a part of the studies on physical properties of Centaurs and TNOs, using ESO telescopes. Here, color results for 32 TNOs and Centaurs (including the distant body 2000CR105)are presented. Merging these measurements with those of the ESO large program (Peixinho et al., 2004, Icarus 170, 153-166) and with the latest results of the Meudon Multicolor Survey (Doressoundiram et al., 2005, Icarus 174, 90-104) we come up with a large and unique dataset of objects, for which we carry out a significant statistical analysis aimed at color-color correlations and at studying color correlations with physical or orbital parameters. The conclusions of these studies tend to confirm the results of the quoted papers. As a by-product of our study, we could identify several possible candidates for light curve future studies.
