Are there any acid-base indicators whose protonated and deprotonated forms have the same number of resonance structures?
In the examples you drew, these resonance structures are not ‘opened up’; they are there in both the protonated and the deprotonated form. However, since the protonated form requires charge separation to access these resonance structures, they are less important.

It rarely makes sense to do resonance structure bookkeeping like you are trying to implement in your question.

Indicators need to display a colour change upon protonation/deprotonation. that can either happen by modifying the structure (e.g. bromocresol green) or by the electronic changes induced by the charge occurring. The latter case will mean some shifting in the orbital energies — most importantly in HOMO and LUMO — and can practically always be explained in a ‘resonance way’.
