Justicia brandegeana, shrimp plant?
I think purple is correct...I have same plant. Can't find a tag right now.
I had it planted outside, and am trying to overwinter one - to get cuttings in early spring to have more to plant outside again.
I normally hang out at c & s with over three hundred plants
but I've been branching out with a few house plants.
It seems I can grow them I just can't seem to I D them.
I found one of the tags from my plant, it says Firecracker flower (Crossandra infundibuliformis).
So I am not sure if it is same as yours - if you google photos, maybe you can tell.
I took few cuttings to try to root them, will see if it works. It looked good in the garden, and literaly no maintenance.
