Does colour affect rate of cooling? Mind blown.

I have learned something interesting this morning from recent paper in Physics Education. The colour of a hot object does not affect how quickly it heats up or cools down. The idea of black objects absorbing more radiation works with visible light but not infra-red. I am sure I should have known this before , but… wow…

Have I understood this correctly?
