Colour of Adenium Flower Deepens as Days Pass!

Noticed that the colour of adenium flower deepens as days pass. This flower has a more beautiful hue one week after blooming! This adenium or ‘desert rose’ had bloomed one week back and I had posted it. Doesn’t it have a more beautiful colour now? As I am growing adenium for the first time, I did not know that adenium flowers last so many days.
