Can't change hint background color in VSCode

[alanhkarp]

I find the background color for hints too dark, so I tried to change it. I can change the hint text color, but not the background color.

1. Go to Settings
2. Change Hint Text Color to rgba(240,0,0,1.0)
3. Look at a warning in a Rust file, and see the text is red
4. Change the Hint Color to rgba(240,0,0,1.0)
5. Look at a warning in a Rust file, and see that the background is still greenish
