The binary diff is best thought of as:

- Built up second string from longest substrings, which can be found in first string.
- color those parts alike.

m_BinDiffColors is the (cycled) array providing these colors.

I.e. the second string will be colored by m_BinDiffColors[0], [1],
etc. according to the matched substrings from first string (from left
to right).

If parts of the first string cannot be found in second string, these will have
the same color as the string in the left display (red).

If parts of the second string cannot be found in first string, these
will have the same color as the string in the right display (yellow).

If the same part of the first string is used many times, "later"
colors take precedence in the first string (e.g. compare "abcXYZdef"
and "ABCXYZDEFXYZIJKXYZLMN").

So you want to have them as visually distinct as possible.
