Incorrect color specification, incorrect item?

So after a week delivery time for the shower head was now finally with us, and was unpacked immediately.
What was first noticed that on the package is already only of the 3 colors (red, green and blue), the speech, the question arises: where is the Purple? Even the name of infactory but nothing can be seen, for Hydro Power. Supplied incorrect item? Well, I do not insist on names ...

First impression: The water pressure is good and the noise really surprisingly quiet, under the flowing water no longer audible.

While playing with the temperatures then I made but the following discovery: green and blue work well, are very bright and not too pushy, but once you shower hot was transformed the relaxed shower fun in a disco, because the LEDs began alternating red and blue flashing , A single red occurs not at all, after the red-blue-flashing it goes directly into the red-flashing, if you already scalded. Too bad, I've been hoping for more ...

Addendum: After an exchange of e-mails in German rather bumpy, I got the money for the shower head to get reimbursed, rather than as requested to get a replacement.
Quick response on the part of the dealer that you have to leave them, but the German was reading more like from a Übersetzungsmaschiene. Phrases like "Please feel free to keep the product. You do not come back to her." had to be unraveled first. Only on the 13 euro shipping I remained seated but for that I was allowed to keep the shower head in spite refund.
