Original Pull Request: https://github.com/microsoft/terminal/pull/10779

State: closed
Merged: Yes

I was watching a video about vectorized instructions and I wanted to
try out some new things, as I had never written AVX code before.
This commit is the result of this tiny Thursday morning detour into
AVX land. It improves performance of TextColor::GetColor by about 3x.

Validation Steps Performed

  • Default colors are still properly shifted +8 ✔️
