These fMRI scans show brain regions activated by sexual desire (in blue) compared to love (in pink) in healthy patients. The overlap in red illustrates how a patient’s brain lesion affected the area in the brain associated with decision-making in love.

I assume the colours selected to represent love and lust have no significance.
Now we have definitions for love and lust.
Lust: Concrete representation of sensory experiences
Love: Abstract representation of those experiences
I guess it's not just visual experiences. You might lust after or fall in love with people just by reading their words without ever seeing them.
"The current work makes it possible to disentangle love from other biological drives,"
