Are you referring to Lightroom's masking capability? Indeed, even in Photoshop it is possible to select a color and perform a masked adjustment. Lightroom's selection/masking tools are pretty good and for basic tasks it is fine, but the masking workflow is (IMHO) fundamentally limited. DaVinci's nodes can be stacked on top of each other and the per-hue adjustments are live. Also... I gotta say that the visualization the DV's tools offer is far superior. At a glance I can see the range of hue that have been selected as well as the degree of change they are being subject to.

FYI, In DV it is possible to edit hue to hue, hue to saturation, hue to luminesce, luminesce to saturation, saturation to saturation and saturation to luminesce. There is also the amazing chroma warp, using which near arbitrary color adjustments can be made. Nothing out there comes even close to that capability. No wonder most Hollywood movies are color graded in DV.
