The white on blue reminds me of high contast color themes for the visually impaired.
Yes, but that same conclusion was also valid back then in 1985.
High contrast color theme for default WB1.x setup was done intentionally, to make fonts more readable and put less stress on eye muscles.
Just one of nice proofs how Jay and original team were clever.
I always set my WB3.1 theme to a close match of one found in WB1.3.... that blue/white is part of original, golden era look & feel.
