You can use ffmpegcolorspace like this:
gst-launch -v videotestsrc ! ffmpegcolorspace ! video/x-raw-rgb ! fakesink

But you don't need ffmpegcolorspace because the videotestsrc can
also output video in rgb. (Try gst-inspect videotestsrc)

To force videotestsrc to use rgb use something like this:
gst-launch -v videotestsrc ! video/x-raw-rgb ! fakesink
