adjusting a Gray image to a bone white

hello does anyone have any suggetions adjusting a Gray image to a bone white? the product is back splash tile its outlines with a white background but it look gray

Lift the white point with Levels or Curves.

But the real problem is that the lighting doesn't match with a pure white background. Most critically, you really need to get rid of that heavy shadow on the right. A white background implies soft and completely diffused light, but that's clearly not the light this was originally shot in.

I agree the lighting is bad but this is how the client wanted the tiles shot it was in a room with no extra lights just over head lights.

I did this with an adjustment layer (Hue/Satuation) and a top layer filled with white and set to Soft Light.

It seems that “Bone White” is a name assigned to many similar colors.  The site shown above displays a hex value that I assume is keyed to sRGB as  #d7d0c0 and comes very close to the pictured sample shown.

This translates to Lab Color : L84 a0 b9

The list to the right of the sample specs CIE L*a*b (rounded) L84 a0 b8

Is that the color you are aiming for?
