Is it only possible to choose between cool white, neutral white and warm white with this product, or is the entire RGB palette also available? I have looked through several sites and there are dealers who offer the product 1x with only white tones and under the same name offer the product with 16 million colours. On the Philips website, only the product with 16 million colours is displayed. In the shop I also saw the product with the RGB selection. However, since the price difference with this product is big and nothing is mentioned in the specifications, I wanted to be on the safe side. Thanks!
