What happen to the Hot Lava Orange color from the 2015 TRD Tundra?

Does anyone know why Toyota went to a new Orange color? New orange looks like a SAFETY Orange color! Current Tundra but looking to replace but want the old Lava Orange.

 

The old color was called Inferno Orange. It was a TRD Pro exclusive color, and then trickled down to lower trims after the first year. Same as all the TRD Pro colors on the Tundra. They eventually eliminate colors that don't sell as well to make room for new ones. Just how it works. No colors outside the standard greyscale are safe.
