ROMANY tiles and Hechinger Paint | merrypad
I found this for you. I think a paint store might be able to figure out from the code on this color chip what formula to use for Dresden Pink. However, the code is incomplete. You might have to infer what it was.
But, honestly, you might never be able to recreate the pink in your memory. So many things influence how we perceive color in a room. Light, the color on the ceilings and the other furnishings, for instance. I'd try for a pleasant pink that you love, and use that. Trying to match what you remember is probably just going to be frustrating. But, you might have a go with the photographed paint chip. Maybe there is enough info for a good paint seller to recreate it. Good luck.
