[edk2-devel] [PATCH v1 3/3] MdeModulePkg/ConSplitter: Change StdErr color to EFI_LIGHTGRAY

[Gao, Zhichao]

I agree the EFI_MAGENTA is not a good choose. But this may be a different issue. Many platforms would set serial port as ConOut and ErrOut. The different colors for them can differ the origin. I don't think change them to the same color is a good idea.

Thanks,
Zhichao
