Change of color after I join meshes with Ctrl+J

Question

I've made a vase which has 2 handles. The handles were created separately so I wanted to join them and used CtrlJ to do so, with the intention to then trim the unneeded vertexes.

But as I join all in a single mesh there's a change in color, like it's no longer being lit properly. What's causing this and how can I fix it?

^{Left Joined, right not joined}

In most cases this happens when one of joined objects had inverted (negative) scale, just in case for future handling with meshes. — Mr Zak, Nov 12 '18 at 14:54

That's a normals problem. You need to flip normals.

Select the whole mesh in edit mode, then go to mesh, normals, and recalculate outside.
