.json and custom visuals with power bi theme possible?

Hi,

Thanks for answer.

Do you know if possible to set the colour of the conditions within this visual?

e.g would like to use if value = -1 then "#.....'

                                  if value = 0 then "#...'

                                  if value = 1  then '#..'

to colour code values shown our colour of green amber red rather than set manually?

Also is there some documentation anywhere which says the name of custom visuals to use?

We also use hierarchical slicer which I'm guessing may have name which not sure of for the local .json

Do you know name to use for this one? 

Thanks again.
