We can notice that on Zed, the hue of semi-transparent layers is skewed towards the higher value color, and this shouldn't happen.

It seems that the Blade rendering backend has some color issues on Windows. I tested your #0080ff80 example using the One Light theme, and here’s what I observed:

• Blade backend: The color appears as #b7c9fc
• On macOS: The color appears as #7cbdfd
• In my DX11 implementation from #13684: The color appears as #7dbdfd

The DX11 backend is very close to the macOS results, whereas both differ noticeably from Blade.

This is because the Blade backend uses Linear instead of sRGB:

Don't close it bot

[SomeoneToIgnore]

Well if it's on Blade, why should not we close it?

[JunkuiZhang]

Well, we can close this, but anyway, we will finally fix this when the dix11 branch is merged
