The original MacPaint taught me this, and it didn’t even have color.

It also had this cool mirror tool that would mirror your brushstrokes on various axes and I spent so much time making cool designs with that, but I’ve not seen it in a drawing program since.

Procreate can do it, and there are specific apps for creating Mandalas.

Source: My wife is a former tattoo artist and used it all the time.

Maaan; I miss classes in the computer room, sitting at those transparent-case crt macs playing flash games and drawing in paint when we were supposed to be doing some assignment nobody gaf about.

Tuxpaint could do that! I should install it again

If I'm understanding correctly, Krita has that mirroring thing in a variety of .... uh... variations.

in Photoshop: brush tool, then click the butterfly at the top

Illustrator is more complicated:

Line Segment Tool (keyboard shortcut \) to draw a straight line across the artboard (twice for 2 axes - horizontal and vertical)

hide the line by changing the stroke color to None.

Go to the Layers panel and click on the circle next to the layer to make it a double circle.

overhead menu > select Effect > Distort & Transform > Transform.

Check Reflect Y and input 1 for the Copies value. Click OK.

gimp/krita/inkscape?

I support them in concept, I don't personally use them because I get Adobe through work.

fair enough, can't share knowledge you don't have, and you know the things you need to.

thanks for sharing what you know.

I only know about the Hitachi magic wand

Magic Wand isn't what I'd use to erase a color. That would be easier with hue shift/color replace. Whatever the hell it's called (i havent used photoshop in quite some time).

Well, I imagine lots of wizard sleeves at the sorcery club ...

Iirc the wand allows selecting the color everywhere in the image, and then any operations applied would show immediate feedback. Not sure the other way works the same, and probably requires going through dialogs again if any adjustments are necessary.
