Ikea LIATORP Sideboard white - How to fix a blemish?

Hello, I have a LIATORP sideboard in white standing in the living room - unfortunately, I have a small (approx. 5 cm) scratch on one corner where the paint is worn off. I would like to touch it up, but I don't know which color to use, since Ikea certainly does not provide color codes. Do you have any idea which shade would match?

Best regards in advance Arno

Take a sample to a paint store or hardware store and have the color shade determined there with the color scanner.
