    Almost.

    Here, I converted your image so that Cb and Cr (blue-complement and red-complement chroma) channels are constant, and only Y (luma) carries any image data, just like the flag.

    Black and white cannot be reproduced unless you adjust chroma to center in those places or allow luma to span outside the 0-255 range.
