A pattern passed down can welcome new colors without losing the reason people recognize it.

Traditions survive by having a fixed part and a movable part. The structure is what makes something recognisable, while colours, materials and details can shift with each generation without breaking anything. Insisting that nothing move is a reliable way to end up with a museum piece nobody uses. Continuity and change are not opposites here.

With something you have inherited, work out which element is actually the identity and which is only the version you first met. Let the second one move. Then say plainly what must stay, so the next person knows where the freedom is.
