All good things take time.

I think it would be fun to mix that with the way the rest of the batfam is drawn when they're in shadows:

the glowy eyes and splashes of vibrant colour, especially with Nightwing's symbol looking like it's actually reflective.

So now I'm thinking:

imagine if Gothamites realized that dangerous people get really uneasy when they keep seeing things that, out of the corner of their eye, might look like a vigilante. To the point that they avoid areas where, let's say, an old poster on the wall is just that shade of yellow that keeps jumpscaring them every time they turn. Or that old trash can that still has a patch of green paint that hasn't peeled away yet. Not even realizing what makes them nervous, just knowing that a particular place makes them jumpy. Stuff like that.

So to keep themselves a little safer Gothamites just start… adding little things like that in their neighborhoods. Nothing that outright references the Bats - stuff like that might get vandalised or just lose the effect if it's recognised, but things like:

- plants on window sills in flower pots or vases in bright colors

- little shiny trinkets in the windows that just might be mistaken for a flash of a utility belt

- colorful curtains get very popular for children's bedrooms

- someone sticking a piece of blue reflective vinyl on a chimney visible from the street, so that as you walk you see a little flash of electric blue when the light from streetlights hits it just right

- people painting a pair of dots with glow-in-the-dark white paint high up on walls by fire escapes or in dark alleys, that look like glowing eyes
