Describe the bug / provide steps to reproduce it

In my opinion, text/foreground colors in zed themes need to behave more like CSS colors.

With CSS, colors replace their inherited color (they do not blend) - the only inheritance that affects the end-result color is CSS opacity values (equivalent to fade_out in our case)

Let's take this scenario as an example, I am building a dark theme with a lot of transparency features and the blurred background style.

My "text" color is #FFF

However, my "hint" color is #FFF4 (a white with a low opacity)

Unfortunately, when these two colors blend, the hint code ends up being completely white.

The only way to mimic an opacity value is to use a color like #888 which is not recommended for accessibility reasons

Environment

N/A

If applicable, add mockups / screenshots to help explain present your vision of the feature

Thinks like "hint" or "predictive" should not be being blended with other colors, I'd even argue that no text colors at all should be being blended

We should be able to achieve things like this with

"hint": "#FFF6",
"hint.background": "#FFF2"

If applicable, attach your Zed.log file to this issue.
