Is the Panton color card required?

I have my own color card, not a Panton one.

And they do not have Aruco markers at the corners.

Could i use my color card by cropping the card only and input as refCard (instead of finding card automatically using aruco)

Or could i copy the corner makers and put at my color card's corners. Would the aruco find my card?

Thank for your efforts. Best wishes.
