Photoshop changes colors from b&w in Lightroom to color in Ph

The newest version of LR is 7.3.1. I suggest you check the CC DTA and update to this newer version.

That was my thought too, though it depends on two questions:

• how, exactly, is the image being opened into Photoshop?
• how, exactly, was the image made to appear as B&W in Lightroom?

If Photoshop / ACR is not successfully applying a given adjustments "recipe" and underlying profile (for whatever reason) under the instructions of LR, then one can force LR to carry out the job instead.

One can do this by setting up a new external editing preset: supplying the location of the PS program, and bit-depth / colourspace / file type options, and saving that configuration under a name. Then instead of just doing 'Edit in PS', you can select 'Edit in PS / [name of preset]'.

LR itself now performs Raw conversion and applies all the adjustments that you currently see, saves the result of that into a TIFF / a PSD file, imports that to the Catalog straight away, and only then tells PS to open that already-saved file up for further editing.

Otherwise (provided LR and PS are of compatible versions) LR supplies PS / ACR a "recipe" for the adjustments, and points it to the file on disk which those should be applied to. And if something goes wrong with executing that adjustments recipe and employing the specified-by-name camera profile etc, a wrong result is seen.
