How do I Return to default Color window in Resolve 15

I am working with Resolve 15 - Beta 1, on a Multicam edit of the concert video and after editing each piece of Music I switch over to Color, on the bottom bar, to do any fine tuning of colour so that all clips have roughly the same ‘look’. This project has 6 musical numbers each approx 5 minutes long.
Originally when I switch to Color I saw in R15 a monitor showing what is playing, this was in the center on my monitor, below which is a small ‘timeline’ so that I can see where I am, and below that are all my Color tools, very easy and logical to use.

While editing last night I switched to ‘Color’ and was greeted by a window, previously one that I never seen before, that displayed some 60 or more thumbnail size images which I have identified as coming from the clips that I have selected.
If I select a thumbnail clip I can then do adjustments to ‘Color’ but it is difficult to know exactly what I am adjusting in relation to its position on the main edit line.
These thumbnails are also far too small to clearly see what I am doing.
How do i get back to my original Color screen.

It sound like you selected the Lightbox mode. Check the workspace menu.

Some time reading the v14.3 manual will help too as this is a pretty fundamental selection.
