Fluorescent proteins are also useful for tracking cell populations, such as tumor cells, in vivo. Thus far, the best tools for imaging in live, whole animals have been far-red fluorescent proteins ...

For a time, however, it appeared that fluorescent protein engineering had hit a 'yellow' wall in efforts to red-shift fluorescence emission. Fortuitously, this barrier had already been surmounted ...
