Color is not claimed as a feature of the mark.
The mark consists of an oval-shaped graphic with the single name RioVista on top of a river-flow graphic that has 2 trees at the end of it. Underneath the river-graphic is the word -Media-. The non-separated RioVista (as opposed to Rio, then space, then Vista) with capital R and V is important, as is the dashed "-Media-" (-Media-). The base font for the name (RioVista and -Media-) is Arial-Rounded Bold, with a shadow. Just above the start of the word RioVista (above the "R") and above the start of the river-graphic (which appears to come out of the "R") is a soft, round, opalescent light.
