The blue is much darker than in the picture, rather purple-dark blue, which I like better, but, nevertheless, it is natural therefore an optical illusion. The fan was as offered by the brand Klarstein. It is quite compact, you have nothing to assemble, it can be equally connected. Is comfortable in size and weight. However, not suitable for larger rooms, where you want to stay longer. Mine was intended for the internal bath to durchzupusten there times. He does quite Doll at the first stage. Pust noise is louder than in other models, it is humming. Thus, only suitable for the bathroom in my apartment, but exactly I wanted. Price-performance ratio is absolutely okay.
