Is it due to diminished conjugation and blue shift out of the visible?

do you have any entry level books on chemistry? (not stuff that give an overview on all chemistry but focus on one part) 😁

It’s due to conjunction. The same way phenolphthalein indicator works.

User1937391028441 :
Wait aren't sulfonic acid groups (especially when attached to aromatic systems) HIGHLY acidic (pKa much lower than typical carboxyllic acids)??? Wouldn't it be the phenol group being protonated and deprotonated in acidic vs basic conditions, resulting in the gain/ loss of colour (since phenols are much weaker acids than sulfonic acids, and thus get protonated to greater extents by weak acids such as citric or ethanoic acid)?
