Orchestrock 

Orchestrock is (to put it simply) a combination of Rock instruments (heavy guitar, drums ect ect) played with a live orchestra.

The occurance of this type of music has been rising as of late, and a first example that would come to mind would (at least) be Nobou Uematsu's "Black Winged Angel" with his own band "The Black Mages" for the CGI movie "FFVII- Advent Children".

Hey man, this Orchestrock is amazing!
What the fuck are you?, insane???, Slayer is obviously better :|

Characterized by a vibrant and harmonious array of colors, reminiscent of the diverse and visually stunning spectrum found in orchids, with an added connotation of fluidity or dynamic variation.

Example sentence: The artist carefully selected an orchistrochromatic palette, infusing the painting with a mesmerizing blend of hues that subtly shifted and evolved, much like the petals of an orchid in different lighting conditions.
