Context: The Very Large Telescope Interferometer (VLTI) has been providingbreakthrough images of the dust in the central parsecs of Active GalacticNuclei (AGN), thought to be a key component of the AGN unification scheme andAGN host galaxy interaction. In single infrared bands, these images can havemultiple interpretations some of which could challenge the unification scheme.This is the case for the archetypal type 2 AGN of NGC1068. The degeneracy isreduced by multi-band temperature maps which are hindered by ambiguity inalignment between different single band images.  Aims: To solve this problem by creating a chromatic model capable ofsimultaneously explaining the VLTI GRAVITY+MATISSE $2\mu$m$-13\mu$mobservations of the AGN hosted by NGC1068.  Methods: We employ a simple disk and wind geometry populated with black bodyemitters and dust obscuration to create a versatile multi-wavelength modellingmethod for chromatic IR interferometric data of dusty objects.  Results: This simple geometry is capable of reproducing thespectro-interferometric data of NGC1068 from K$-$N-band, explains the complexsingle band images with obscuration and inclination effects, and solves thealignment problem between bands. We find that the resulting inclination andposition angle of the model is consistent with those inferred in previouslarger scale studies of the narrow line region. Furthermore, the resultingmodel images visually resemble the multiple achromatic image reconstructions ofthe same data when evaluated at the same wavelengths. We conclude that the AGNof NGC1068 can indeed be explained by the clumpy disk+wind iteration of the AGNunification scheme. Within the scheme, we find that it is best explained as atype 2 AGN and the obscuring dust chemistry can be explained by a mix ofolivine silicates and $16\pm1\%$ amorphous carbon.
