Very close, but not actually correct.
The black pyjamas ARE from Kabuki theatre, and stagehands (called Kuroko) did wear them - not so they would blend into shadows (which would render the stagehands useless, as they couldn't actually manipulate props, set pieces, or the stage (all of which they often did while the play was still going on) without coming into the light), but because the audience was conditioned to ignore anyone on stage dressed all in black. This technique is used in Kabuki, Noh, and Bunraku, where the stagehands or puppeteers would be fully visible on stage - sometimes black backgrounds are used to make them harder to see, but that's not always the case, or desirable.
Here's the Wikipedia article on kuroko, which has a picture of one...clearly showing him kneeling right behind an actor. (That appears to be a Noh play, not Kabuki, but same idea.)
And that's why they're portrayed in black pyjamas - not because they were trying to hide at Kabuki shows, but because being in black pyjamas equalled 'invisible' in Kabuki (and Bunraku, and Noh), so showing a ninja dressed all in black was shorthand for their being invisible, while still showing them. And, in the actual plays, when the guys in the black pyjamas became active characters on stage, that would amount to coming out of nowhere so far as the audience was concerned. Instant ninja stealth, without having to go through the trouble of making special effects.
Actual ninja wore whatever was convenient to get at their target. If their target was going to be at a Kabuki show, then, dressing as a stage hand
may have been useful... But not likely. Blending into the audience would have been more useful to a ninja, unless their target was an actor, stagehand, prop, costume, or whathaveyou. (All highly unlikely circumstances.)
Even then, it'd be more convenient for thefts, than assassinations - ninja weren't suicide warriors. They were supposed to get out of their adventures alive. Killing someone in a public place - especially bursting off a stage during a play and attacking them, in full view of the rest of the audience (rather than coming up behind them and quietly sticking a dagger in their back) - is not really conducive to this. (Although, if that's the only way to get at the target, well, maybe you'll have to.)
A ninja would be dressed as someone who belongs there, wherever there is - a peasant working in a field, or a wandering monk, or a merchant, or a samurai in armour (and many known or suspected ninja were actually samurai), or just a random regular person who happens to be there.
Even at a Kabuki show, if not in the audience, they'd be better off as actors than kuroko. Kabuki actors were known to double as prostitutes (which got early forms of Kabuki banned), and a ninja get the target in a vulnerable position that way. Even if they chose the wrong (non-ninja) actor to bed, that leaves them distracted enough to have a dagger slipped in their back, or their stuff stolen. Not as useful for dragging information out of them than having them hire you, though, so a bit hit and miss if you're trying for that.
The point was to not be noticed - wearing black pyjamas is not going to accomplish that except under very, VERY rare circumstances.
It IS possible that ninja sometimes wore black pyjamas when they were sneaking around at night, when visibility is already low, but generally 'looking like you belong there' was far more useful, even at night. (So far as I know, there's no actual contemporary reports of actual ninja doing so, but...well, if it was a 'sometimes' thing rather than SOP (as it was), and they didn't get caught while doing so, there wouldn't be, would there?)
So, yes, ninja
were like spies today - who
also don't typically skulk around in black pyjamas.
