Favicon for RISE and REVIEW

Hi

This may seem a weird request, but can the favicon for RISE and REVIEW be slightly different please?

I'm finding, when teaching colleagues to work in the two sites, they often think they're in one, when they're in the other, lol.

If they're on a single screen and working in both platforms, it seems to cause confusion. 

Just feedback based on my experience.

All best

JR
