Why is my 1TB WD Blue in no printed pack also front is not in blue

In Japan I have purchased laptop WD Blue 2.5 HDD but strangely it was in a brown card board pack. Inside there is an air bubble packet the HDD 1TB with guarantee (in Japanese). Just in curiosity I wanted to know WD do sell HDD in non printed packs. Hope it is not fake. I wish I could add screen shot of a package as I am new I do not know.
PS: note though it is WD Blue but there isn’t any blue color just printed text.
Thank you.
