The hit indication color difference between Java and Bedrock is different by far. It's an odd "bug" that shouldn't affect gameplay if anyone was to make a parity change to match the two. This problem has been presented in Bedrock since it was first released. To help illustrate this, I have provided two images of the same creature. Java is the one with the hot bar and bedrock is the one without. And as you can see, the two are extremely different. If this was to be fixed bedrock would feel even more like Java and it would be a simple fix!

How to reproduce this: Hit a mob on either edition and compare!
