Mapping with coloured numbers

Good morning everyone,

I was wondering it there is a way to visualize the direct sun hours directly in 3d but with numbers instead of coloured meshes. So for example wherever there is yellow there will be a +6 instead and where there is blue there will be a 0.
It would be nice also to have these numbers coloured the same way.

Thank you!
